First Talk on Science Results
I've given several talks to friends and colleagues about my experiences in Antarctica, but I gave my first talk on the scientific results at the Astrobiology Science Conference in League City, Texas, yesterday. It was well received and I got some good questions. Here are my slides: My talk followed two on the Endurance robot that was exploring Lake Bonney down the valley from us at Lake Joyce. I claimed that Ian and Dale were highly sophisticated observers that beat out any robots. It's important to say where you were. And to describe the regional context. Lake level rise is one of the big stories. The yearly data until the 80's are from surveys by NIWA, whereas the lower graphs show the depth of the salty layers in three different years, including our data. Both show that lake levels are sometimes stable for years and often rise rapidly. I started with the shallow mats and worked my way deeper. Chla is the concentration of chlorophyll a. AFDW is the
