Love science, #Antarctica and charismatic megafauna?

Read this fantastic @ConversationUS piece by MOO team member Lisa Munger!

Check out the video spectrograms of the newly-discovered *ultrasonic* calls of Weddell seals, recorded under the sea ice in #Antarctica. Biology is full of surprises!

The calls are played at native frequencies, then shifted down so you can hear them.

[McMurdo Oceanographic Observatory @MOOAntarctica]

Weddell seals in #Antarctica regularly produce *ultrasonic* vocalizations! High-pitched sounds that humans can't hear.

For communication? Echolocation in absolute dark of #Antarctic winter??

Today's @uoregon news about our discovery:

Here's a video of a Weddell seal making an *ultrasonic* chirp call under the sea ice of #Antarctica.

Head/chest move, but no air escapes the mouth-air is just moved around internally.

Presented in real time, then slowed down so you can hear the chirps. https://t.co/wjgoH8XIWO

Nine recurrent ultrasonic call types discovered in @MOOAntarctica's acoustic dataset - from under the sea ice in McMurdo Sound, #Antarctica. We don't know the functions of the ultrasonic calls. Echolocation? Communication? Full video: https://t.co/WoVDjgZsPQ vid: Henry Kaiser

Weddell seals produce *ultrasonic* vocalizations! We published today in @ASA_JASA. First seals known to regularly use high-pitched sounds that humans can’t hear. https://t.co/VyYMZH79aQ See fun summary VIDEO 👇🏾👇

Check out this fantastic new NOVA segment about our little fishing, diving, and research community in #Antarctica, and our research on un-frozen #Antarctic fishes! Their presentation of the science is spot on. @NSF_OPP @uoregon @novapbs https://t.co/XsxapzYpl8

Our final (FINAL!) LIVE video stream from under the ice in McMurdo Sound, #Antarctica. Starts in 10 minutes: https://t.co/m5RGgpkF1G

[McMurdo Oceanographic Observatory @MOOAntarctica]

Today: Last chance to watch LIVE under the sea ice in McMurdo Sound, #Antarctica. Neat critters, incredible sounds, informative commentary. 2pm Pacific Time, US: https://t.co/m5RGgpkF1G

[McMurdo Oceanographic Observatory @MOOAntarctica]

LIVE in 30 minutes: tune in to hear the otherworldly vocalizations of Weddell seals, broadcast from under the sea ice in McMurdo Sound, #Antarctica. https://t.co/m5RGgpCgqg

[McMurdo Oceanographic Observatory @MOOAntarctica]

Final two LIVE underwater broadcasts from MOO under the sea ice in #Antarctica: Live audio tomorrow & video the following day (Thurs. 10:30am & Fri. 2pm, PT in US). Link and schedule: https://t.co/FTZytzWTCJ

Unfortunately, due to a technical issue, MOO's live stream for tonight has been postponed TBD.

[McMurdo Oceanographic Observatory @MOOAntarctica]

Check out what's happening *LIVE* under the sea ice in McMurdo Sound, #Antarctica. Tomorrow, Tuesday* 6pm Pacific Time. Link and schedule: https://t.co/FTZytzWTCJ

@BillyOcean718 There is. The Air Force (McChord AFB, C17s) and Air National Guard (NY 109th, LC130s) support the intercontinental airlift, and LC130s to S. Pole. The Navy (MSC, NCHB) runs shipping and offload. Coast Guard breaks ice to get ships to McMurdo Station. Info: https://t.co/zTcmB9UL8F

LIVE now, from underwater in #Antarctica.

@nickrsan @NSF_OPP The MOO's periscope attachment, of course! Just kidding - it's from one of USAP's public webcams: https://t.co/HXcWnjy1VX

Timelapse: Over the winter, some hardy souls started building a new IT building @ @NSF_OPP's McMurdo Station in #Antarctica. 2nd phase starting now. Improved network and internet could facilitate needed ocean observing, like an improved @MOOAntarctica. https://t.co/6SjEzh4Txu
