Growing up in Chillicothe, Illinois, Alice Eilers dreamed of becoming a teacher. Ms. Eilers began her schooling at the University of Mississippi, receiving her undergraduate degree in Elementary Education in 1990 and completing her graduate degree at the University of Memphis six years later. In 1995 her dreams of becoming a teacher became a reality and she began her teaching career at the Pink Palace Museum in Memphis, Tennessee. Ms. Eilers is currently the Manager of Education and has had the pleasure of teaching a variety of subjects including astronomy, natural and cultural history to area Pre-K through 8th grade students. Ms. Eilers has also been involved in number of national teacher professional development programs. In 2008, she was selected to participate in a research project studying Leatherback Sea Turtles through the NOAA Teacher at Sea Program. Ms. Eilers is in the MESSENGER Educator Fellowship Program and has also participated in the UMASS-STEM Polar Connections Program.

February 21, 2012 Reflections

No looking back
Reflections from my PolarTREC Journey Where it all began While the actual 'Weddell Seal in the Ross Sea expedition' went from January 6 through February 20, my expedition started much earlier - a year earlier in fact - when I was selected for the PolarTREC program in January of 2011. One month...

February 20, 2012 Life at McMurdo - Part two

Burgee
Life at McMurdo - Part two Since we've tagged the last seal - 21 in all - I've had a 'wee bit of time' (that's what they say in New Zealand) to explore McMurdo. Join me on my tour. Housing My first day on the 'Ice', I met Autumn who works in 'housing'. Let's find out what she does at McMurdo.

McMurdo Station
Life at McMurdo Station Wow! It's hard to believe my time in McMurdo is coming to an end. From the moment I stepped off the plane it's been like a foot race - hurrying here, hurrying there, and trying to get everything done! In fact, it's been so busy, I've missed the 'Welcome to McMurdo'...

Insulation - Video Journal This journal is brought to you by: • The students at Jackson Elementary They wanted to know... What kind of insulation works best for marine mammals - fur or blubber? That's a great question. Let's investigate! Enjoy the video and be sure to try out the activity!

Project Information

McMurdo Station
5 January 2012
21 February 2012

Where are They?

The team will be based in McMurdo Station, Antarctica. McMurdo Station is on Ross Island, a volcanic island (with the southernmost active volcano, Mt. Erebus) south of New Zealand in the Ross Sea. The team will travel daily to seal haul outs and work on the sea ice outside of McMurdo Station.

What are they Doing?

Weddell seals live in the region surrounding Antarctica, and spend their time on sea ice and in the water. They get most of their food from the sea, eating fish, krill, squid, and crustaceans. They are able to stay underwater for about 80 minutes while they look for food, and are known for making very deep dives of up to 700 meters (2300 feet).

The research team is interested in learning more about Weddell seals by studying how they dive and forage for food during the winter when days are shorter and there is more sea ice cover. They are also interested in collecting oceanographic data, such as water temperature and salinity.

The research team will collect this information by traveling to places where Weddell seals are hauled out and briefly capturing them. Once they have captured a seal, they will conduct an exam in order to determine its health and condition. The researchers will also put a satellite-linked dive recorder on each seal they capture. These devices will transmit data showing where, how often, and how deep the seals are diving. In addition, the devices record the temperature and salinity of the water where seals are diving.

Currently there is not a lot of information about how Weddell seals find food during the winter. Without this information, it is difficult to predict how seals will respond to changing environmental conditions. By using the seals to collect ocean data, the team is collecting important information which will be used to develop models to predict the role of the Southern Ocean in global climate processes.
