Current U.S. AMLR Field Season

2015-16: U.S. AMLR's 30th field season working in the peninsula!CSlogo

After a few travel challenges, the 2015 Cape Shirreff opening crew arrived in Punta Arenas, Chile on the 17th & 18th of October to begin the 2015/16 field season at the AMLR field station on Livingston Island.  AMLR researchers departed Punta Arenas for the Antarctic aboard the R/V Laurence M. Gould on 22 October.  Fortunately, a lull between low pressure systems allowed for relatively mild sea conditions while crossing Drake’s Passage. We arrived at Cape Shirreff on the morning of Monday 26 October.  Studies at the Cape will continue through until early March 2016.

Weekly reports are posted below.

Coming in 2016 - another U.S. AMLR Program winter vessel survey 

Stay tuned - we will head south on another winter adventure and will share details with you here as we finalize our plans.

CopaLogoGot Birds?
Copacabana does!

Copacabana research is underway!  The Copacabana site was opened on Friday, January 8th.  Camp had been unoccupied for roughly one year prior to our arrival, but all power, heat, lighting, water, appliances and two-way radio communication systems were quickly returned to operational status upon arrival.  No major damage to the camp was apparent and all outbuildings, storm shutters, stored equipment, and food supplies were in good condition.  For more details, read the sit reps (see table below) sent in from the island.

Who am I?
Identifying Orcinus Orca in the peninsulaPhoto by Bob Pitman. Orcinus Orca, Rothera, January 2009

In collaboration with the MMTD, Bob Pitman heads to Antarctica early February to participate as an invited scientist aboard the tour vessel National Geographic Explorer. He will be aboard for a month, with the work divided into two legs. Sailing from Ushuaia, Argentina, the first leg is a 10-day trip to the Western Antarctic Peninsula (WAP) and back; the second leg is a 20-day trip that also includes the Falkland Islands and South Georgia. While on board, Bob will look for a top marine predator, the killer whale Orcinus Orca.  Normally, when he finds them, the ship diverts to allow the passengers to view the whales, and then after about an hour or so, Bob and his assistants will deploy in a small boat to photograph, biopsy sample, and satellite tag individual whales. Through this effort, the research team has acquired over 60,000 images of four different ecotypes of killer whales from the Scotia Sea/Antarctic Peninsula area and scores of biopsy samples.  Additionally, they have tagged over 75 killer whales and five Antarctic minke whales to date. Bob and his colleagues are just beginning to organize a photo-identification catalog for WAP killer whales, which will allow the research team to make population estimates for the three main types of killer whales that occur there (types A, big B and little B). This year, they purchased a UAS with grant funding, and MMTD colleague John Durban is currently on the Explorer taking aerial photographs of killer whales (and minkes and humpbacks!) to determine body lengths (for killer whale taxonomy studies), as well as health and body condition (as determined by length/weight ratio). This is the sixth year of research on board the Explorer, sponsored by the National Geographic Society and Lindblad Expeditions in grants made available to Bob Pitman, John Durban and Holly Fearnbach.
