Data from the MOO is archived for future study and made available to the world as quickly as possible. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521835917640-2WZBR1IZNT2PV0JW9MPT/Presentingkiosk_co_cr.jpg About the Observatory, under the sea ice in Antarctica The MOO project leader explaining the workings of the live data kiosk to McMurdo Station personnel. Currently, live images are available to the public via the internet. McMurdo Station personnel can access all live data, audio and video. As station capabilities improve, the full data feed will also be broadcast to the world. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521840321611-ZWAKESR8WA9JEI81F27M/freezeproof2_cr.jpg About the Observatory, under the sea ice in Antarctica An Antarctic notothenioid fish nestled among anchor ice in freezing seawater. The Observatory project is aimed primarily at supporting studies of these fishes that dominate the Southern Ocean. They've evolved special adaptations, such as having antifreeze proteins circulating in their blood, that allows them to survive extreme conditions that would be lethal to most other fish species. The Observatory is helping us understand the challenges they face in their icy habitat. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521840871192-59UH6DQVTSCJCTP8QPD4/CTDdataKiosk_Black.png About the Observatory, under the sea ice in Antarctica A sample of the live ocean condition data measured by the Observatory. Basic oceanographic data such as seawater temperature, salinity and tides are recorded continuously. For the first time, we now have a formal, long-term seawater temperature monitoring effort in the world's southernmost accessible marine environment–McMurdo Sound, Antarctica. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521841421145-WW2AA08HL3BE1WZ7498W/MOOvideocompilation.png About the Observatory, under the sea ice in Antarctica Examples of the video recorded by the McMurdo Oceanographic Observatory. The self-cleaning, live-streaming HD camera can point and zoom in any direction. By being cabled to shore, we can view video in real time at McMurdo Station, Antartica. Due to internet limitations in Antarctica at this time, only frequently-updated images can be made available to the internet. A daily video tour is recorded, and still images from more than thirty viewing angles are continuously recorded in order to ultimately assemble multi-year timelapse images that will reveal how the under-ice environment changes over time. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521840001667-ZWQB4NLKLPM8LYD4VISI/Spectrogram_Moo_Kiosk.png About the Observatory, under the sea ice in Antarctica An audio spectrogram–a visual representation of the sounds recorded by the Observatory. Our underwater microphone records full-spectrum, high-resolution audio at all times. In analyzing the recorded vocalizations of marine mammals, for example, we can better understand which species frequent this frozen realm and gain insight into their behaviors. We may also characterize the condition of the ice cover, by listening to how the sounds of its groans, creaks and cracks change throughout the year. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521845568125-FQZAX58VK6FGBPTLOCAS/ScallopFishAndIce_co_cr2.png About the Observatory, under the sea ice in Antarctica A young notothenioid fish and juvenile scallop piggyback on an adult scallop nestled among the anchor ice on the shallow sea floor in McMurdo Sound. With antifreeze proteins in their blood, the fishes are well protected against freezing. Invertebrates, like these scallops don't risk freezing internally, like the fishes do, but could be smothered or carried away by ice growth on their bodies. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521846047680-G040M28PIJIQQ603EDLD/sponge_co.jpg About the Observatory, under the sea ice in Antarctica A diver inspecting a large barrel sponge while diving in McMurdo Sound's supercooled seawater. In the glare of the diver's flashlight you can see small ice crystals floating in the water column. These crystals sometimes appear when the seawater is slightly below its freezing point–a phenomenon unique to Antarctica's coastal areas. Seawater supercooling may increase the risk of freezing to the fishes and invertebrates. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521846159938-I8H0H5HWUXJXLNLCON3B/urchinice.jpg About the Observatory, under the sea ice in Antarctica An urchin covered in anchor ice on the shallow sea floor in McMurdo Sound, Antarctica. In this extreme southern marine environment, supercooled seawater is common for about half of each year, driving the growth of ice crystals in the water column and on the shallow sea floor. This urchin may be lifted off the bottom and carried away by the buoyant crystals attached to its spines. It could then freeze into the sea ice cover or be deposited in an unfavorable habitat. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521846274288-8KRWFBVYP543EF3ECMOH/DivingGHHeros_co.jpg About the Observatory, under the sea ice in Antarctica Paul Cziko and Henry Kaiser preparing to plunge through a sea ice crack at a remote field site 90 miles from McMurdo Station. Scientific divers in McMurdo Sound are treated to a phenomenal underwater environment teeming with unique life forms inhabiting varied habitats. On a windless midsummer day with 24-hours of sunlight, such as this, the conditions are ideal for diving out in the open. At remote sites, diving through stress cracks in the sea ice cover is easier than creating our own holes. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842473272-FPTMH6HFMD8XCJHGQAMQ/MOOInTheLab_co_Cr.jpg About the Observatory, under the sea ice in Antarctica Testing the MOO in the lab in Antarctica prior to deployment. The primary engineering for the project was completed by View Into the Blue underwater webcams in Boulder, CO in collaboration with the project leader, Paul Cziko. To deploy the equipment in near-freezing water and without access for months at a time, our Antarctic observatory presented novel engineering challenges and careful planning. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842487037-MUS5PAAT4Y4A3FES9FXS/DeployingConcreteBlock_greg_co_cr.jpg About the Observatory, under the sea ice in Antarctica The team working together to sending the concrete anchor blocks to the bottom of the sea through eight feet (2.5m) of sea ice. Four concrete blocks, weighing from 200 to 3,500 pounds (90 to 1,500 kg), make up the anchoring system for the MOO's scientific instruments in this harsh environment. Without these (or even with) the MOO could be knocked over in dangerous ocean swells, floated away by accumulating anchor ice, or pushed around by the small icebergs that venture into the shallows around our research site. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842519077-8UI4WTUUNK87V5HS1IBX/InstallingBlockAirFilledLiftBag_co_Cr.png About the Observatory, under the sea ice in Antarctica McMurdo Station Dive Supervisor Steve Rupp placing the concrete anchor blocks on the sea floor with the help of air-filled buoyant lift bags. McMurdo Station's expert ice divers, Rob Robbins and Steve Rupp, helped our team's scientific divers with the heavy lifting such as moving up to 3,500-lb (1600kg) blocks of concrete under water and installing an 80-foot-long (24m) steel pipe to protect the MOO's cable from ice movements along shore. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842457482-YFD70H7K9RTEO7526I31/LevelingBlock2_co_cr.png About the Observatory, under the sea ice in Antarctica Paul Cziko leveling the camera's attachments prior to its installation. Installing the MOO required quite a bit of underwater construction: In about thirty, forty-minute dives we choose the precise location for the anchor blocks, bolted on equipment, ran cables to the surface and made numerous critical underwater electrical connections. All with frozen hands, seventy-feet down (21m) in 28°F (-2°C) seawater. (Someone has to take the photos–Henry Kaiser, was with Paul on every dive) https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521843022788-DRCFKRQFKO0XZYGGSIHQ/DrillingHole_co_cr_bl.png About the Observatory, under the sea ice in Antarctica Paul Cziko and Konrad Meister supervising as the MOO's installation hole is drilled in the sea ice cover for diver access. While in the past we've chainsawed, melted and dynamited holes in the ice, the preferred method near McMurdo Station these days is with the fabled Reed Drill. This machine, towed behind a bulldozer, can drill 48-inch-diameter (1.2m) holes in sea ice up to 22ft thick (7m) in just a few minutes. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842784745-2GS9XGWGM5SAOP9EHFPB/PlacingCamera_co.png About the Observatory, under the sea ice in Antarctica Paul Cziko placing the HD video camera, with it's self-cleaning glass dome, on the anchor block. All electrical connections for the MOO were made wet, with cold hands wrapped inside greasy dry gloves. Any mistakes in making these critical matings could have resulted in rapid system failure–an untenable result given that replacement parts can take weeks or months to arrive in this remote location. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842908067-0975TUE0IK7TBGEYY1W8/ComputingoniceNick2_co_cr.jpg About the Observatory, under the sea ice in Antarctica Programming the data collection and archiving schemes–while wearing insulated gloves. Working under the US Antarctic Program's strict security rules, the limited computing infrastructure in Antarctica, and under a grueling deadline, our programmer, Nick Santos, developed our data collection and archiving schemes, mechanisms to transmit data to the internet, and a beautiful data viewer to explore the collected data products (currently only available at McMurdo Station). https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521842768408-G5WTKY5VOKJW75EPZMG2/GoingHome2_co_cr.png About the Observatory, under the sea ice in Antarctica There's only one way out from under 8-foot thick solid ice. Paul Cziko heading home after a working in the freezing water of McMurdo Sound. Divers must have excellent surface support and be mindful of the risks that diving in a remote region far away from advanced medical care. All told, the Observatory took about 30 dives to choose the site, install the equipment and test the functionality. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521659350066-EVIQ6AXWN723JY98QITC/BorchInIce_co_cr.png About the Observatory, under the sea ice in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521659770795-AR0KZ9HFFBYAZ87LNCAN/MOOInstallDiveShack_co.png About the Observatory, under the sea ice in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521660159044-AU7ZH8BDL0A4GM4PB0N1/tpenah_co.jpg About the Observatory, under the sea ice in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521660255104-AU0J7LV1N9UNGZ3SCJHL/CameraGoingIn_co_cr.png About the Observatory, under the sea ice in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1521660463554-BADV57XE9AL9QP7FN7JX/MooFromAboveDark2_co.png About the Observatory, under the sea ice in Antarctica https://moo-antarctica.net/blog daily 0.75 2021-02-09 https://moo-antarctica.net/blog/2021/2/9/across-acoustics-jack-terhune-ultrasonic monthly 0.5 2022-03-11 https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/4a9e2e4e-6ddc-46dc-875c-041073fc49c9/Jack.png Blog - Across Acoustics - Dr. Terhune Discusses Ultrasonic Vocalizations in Weddell Seals Dr. Jack Terhune https://moo-antarctica.net/blog/2021/2/9/max-planck-ice-free-in-icy-worlds monthly 0.5 2022-03-11 https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/6b8535c1-06e6-451e-9b85-3080c54ff48b/scallop.png Blog - Max Planck Institute - Ice-free in icy worlds: Special shell protects Antarctic scallop from ice build-up.

On this particular day, members from our team used a profiling CTD (an instrument lowered from the surface through the water) and detected supercooled water to an unusually great depth. The light blue line shows the actual seawater temperature with depth, and the red line shows the calculated seawater freezing temperature (a function of seawater salinity and depth). In the top 40m (130ft) of the water column the actual seawater temperature is below the freezing point - it is supercooled. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522190184907-YKE0PQWXBJL93R1EGM8K/sponge_co.jpg Ocean condition data recorded by the underwater Observatory in Antarctica An upside-down underwater snowstorm. During this dive, just before the CTD cast of the previous image was taken, our divers were swimming in a bath of shimmering ice crystals. Shown at 30m (90ft) depth, the ice crystals were small but can be seen as white flecks in the glare of the diver's flashlight. Nearer to the surface, some were the size of a penny. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522387215954-KJI9SK783YGOO0SIIR3P/AnchorIce_jetty_co_cr.png Ocean condition data recorded by the underwater Observatory in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522180605375-806K97UO4LZT9MCJN8WN/Platelet+Ice+on+Line+Erebus.jpg Ocean condition data recorded by the underwater Observatory in Antarctica Ice platelets attach to almost anything placed into McMurdo Sound. This rope was hung overnight in the ocean from an ice hole at the surface. When pulled up the next morning, the top 30m (100ft) was covered with ice crystal platelets about the size of a silver dollar. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522180820678-SNJ8ISVSVFWZW2NVBHVS/icedive_co.jpg Ocean condition data recorded by the underwater Observatory in Antarctica Anchor ice growing on the sea floor. In shallow areas of McMurdo Sound, ice crystals attach to the rocks and sediment that make up the sea floor, as well as to almost any other surface. If the ice continues to accumulate, the buoyancy of the ice will ultimately cause large sheets to rip off the bottom–bringing rocks, sediment and invertebrate animals to the underside of the ice ceiling (sea ice) where they will ultimately freeze in. In the background, a thin steel cable attached to a temperature logger has become enshrouded with ice, floating up and forming a picturesque arch. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522181481110-M4UMVM2NM1MCMVZNC7ZO/icecolumn_co.png Ocean condition data recorded by the underwater Observatory in Antarctica Only the shallow sea floor is impacted by anchor ice. Because the freezing point of seawater decreases when the pressure increases, anchor ice (as shown here petering out with depth) occurs primarily in the shallows. In McMurdo Sound we often see a rather distinct line below which the ice doesn't occur. This line indicates approximately the average depth to which the water is supercooled. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522180868107-8KH1TRIU0GBSPYW2ZL8P/icebed2_cr.jpg Ocean condition data recorded by the underwater Observatory in Antarctica Anchor ice is a unique (and potentially dangerous) habitat for cold-blooded marine animals. In being loaded with antifreeze proteins, this notothenioid fish doesn't risk freezing to death even in the presence of ice at water temperatures almost 1°C (2°F) below the expected freezing point of its blood. Instead, fishes like these, and lots of invertebrates too, use anchor ice as a resource. The crevices in the ice crystal matrix are a great place to hide from predators while waiting for the next meal to drift by. Under supercooled seawater conditions, however, ice crystals may invade the bodies of the fishes, potentially accumulating to a lethal load. https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522389316905-1YWM78606DEZI196N11B/LIMA_Antarctica_all_small_rotated_annotated_trans.png Ocean condition data recorded by the underwater Observatory in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522175091448-RC1ROD1OCFKWKI44UL44/Part_MOO_CTD_20180326_Website.png Ocean condition data recorded by the underwater Observatory in Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1522522783883-SGJM2U907IUGO89NM3WX/McMurdo_Sound_Annotated-final-01.png Ocean condition data recorded by the underwater Observatory in Antarctica https://moo-antarctica.net/live daily 0.75 2021-10-19 https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1523000412519-5FNG58X0GNJOZ5BEUV9G/image-asset.png WATCH LIVE under the ice in McMurdo Sound, Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1515612223231-VMSU0IXSVZYLFAG2P2PE/Sample_CTD.png WATCH LIVE under the ice in McMurdo Sound, Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1568675316233-GXPY5MBZ7QZII8ETTV8W/Live_Video_Website_simple_buffer-01.png WATCH LIVE under the ice in McMurdo Sound, Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1515626218856-FF2URA1BLX710XP44HW6/Location+Icon_border.png WATCH LIVE under the ice in McMurdo Sound, Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1515609982663-LLSWOAEBU2M55FE8QI49/MOO_Interface+Demo-offline.jpg WATCH LIVE under the ice in McMurdo Sound, Antarctica https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1515611022966-EVD1KO2QQ8HW64BDF7F7/Sample_Video.png WATCH LIVE under the ice in McMurdo Sound, Antarctica https://moo-antarctica.net/people daily 0.75 2024-10-11 https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1511310054749-HKO58LLIT0O8OWG9JKDI/NickSantos_Moo_Profile.JPG People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1538731887009-JDXXGJ55LQF7LWXT77OD/B195M_Logo+2018.png People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1542924972262-1ZMMZV42SJA6Z56J8FGA/IMG_7962.png People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1511307001504-SUFN2BHQNPWC13VUWUJE/KonradMeister_MOO_Profile.jpg People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1511307167452-79M0XXPLDURGUBO82RIF/HenryKaiser_Moo_Profile.jpg People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1608188160725-OGAAJGWE7KO1N987BPTK/Jack+Terhune.png People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1511257887715-CN2K4587LG5PI52M0QY3/PaulCziko_MOO_Profile.jpg People that made the McMurdo Oceanographic Observatory possible . https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1607819001579-VGFCS07DQYMH9OA5PG9Z/matthewHolmes.jpg People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1542943290375-1P8FFAVGHGT41YYE02KV/20181118_161111.jpg People that made the McMurdo Oceanographic Observatory possible https://images.squarespace-cdn.com/content/v1/5a12ac25c027d8fee9322aad/1515224063718-0APAAOFVXOEM15VUE5GF/ArtDeVries_MOO_Profile.jpg People that made the McMurdo Oceanographic Observatory possible - Arthur L.
