✧ leopard seal ✧

The leopard seal (Hydrurga leptonyx), also known as the sea leopard, is the second largest species of seal in the Antarctic, after the southern elephant seal. Its only natural predators are the killer whale and possibly the elephant seal. It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, birds and fish. Together ...

Two interesting cases to investigate #Arctic and #Antarctic #SeaIce anomalies:

1) Northern tip of #Greenland and Wandel Sea

2) Eastern #Weddell Western Indian #Ocean Sector

Animation from AMSR2 passive microwave observations of the last few days.

In the past 10 years, the #Antarctic #seaice extent has taken on the same pattern as that seen in the #Weddell Sea.

Furthermore, the sea-ice extent in the Weddell Sea also hit an all-time low in May of 2023.

Striking high-temperature anomalies📈 are reflected in record-low sea-ice extent📉 in the #Weddell sea, (and the Western Pacific sector) and record-low for the entire #Antarctic sea ice as well.

The map shows the anomaly of sea-ice concentration in the first week of May.

And now the #Weddell Sea ice extent dropped down to the second-lowest on record.

The #seaice in the #Weddell Sea now has the 3rd-lowest extent on record for this time of year. The extent was lower only in 1981 and 1999.

The concentration map shows the anomaly within the first 11 days of April.

Status of the #January #seaice in the #Antarctic:

- Sea-ice extent was clearly *record-low* for January this year.
- Large negative sea-ice anomalies are seen in #Bellinghausen, #Amundsen/#Ross, and even an open-water region in the eastern #Weddell Sea

Under Antarctic Ice
This 15 min amazing video with sound shows underwater imagery from #McMurdo Sound, #Antarctica:

when he joined our NSF-funded Weddell Seal research project as outreach cinematographer. He did the diving, took and edited the video, and created the soundtrack - that is him playing the guitar, and he also used recorded #Weddell seal vocalizations.
This is an amazingly beautiful video to sit and enjoy during the holidays.
Happy Antarctic Holidays!
