Mindy Bell grew up on an island in southeast Minnesota. Swimming in algae-laden waters, ice-skating around beaver lodges, and watching the wetlands come to life in the spring were instrumental in her decision to study science. Her liberal arts education at Carleton College included a term studying marine science on Catalina Island and at Hopkins Marine Station, where her fascination with marine life was fueled, yet her passion was for teaching rather than scientific research. After graduation, she took the ferry to Alaska and started teaching. After five years of teaching grade 7 to 12 science in Skagway, Alaska, and running a school fish hatchery, she attended the University of Washington in Seattle and earned a Masters degree in Biology Education. Ms. Bell now lives in Flagstaff, Arizona, where she teaches secondary science at the Flagstaff Arts and Leadership Academy.

Stacy Kim is an adjunct professor at Moss Landing Marine Laboratories in central California. She completed her Bachelors degree at UCLA and her Ph.D at Woods Hole Oceanographic Institution. Dr. Kim studies benthic ecology – how animals that live on and in the seafloor interact in communities. She hopes that this project, which links biology and engineering, will set an example for students of how different interests and skills can merge to solve a single set of problems. Dr. Kim has previously hosted a teacher in Antarctica through the ARMADA/TEA program. The experience taught her how better to connect with younger students and enhanced her education and outreach efforts with local schools and clubs. She hopes in particular to engage women and minorities in fields where they are traditionally underrepresented.

What were they doing?What were they doing?

The research team was exploring remote regions of the seafloor around McMurdo Station, Antarctica with a newly developed remotely operated vehicle (ROV) for underwater research. The new ROV can be deployed through a small (15 cm) hole in the sea ice, enabling access to regions beyond scuba diving depths (at 40-170 m). The researchers located historical experimental structures on the sea floor around McMurdo Station and investigated the colonization of these structures by species of sessile invertebrates. This provided an unprecedented opportunity to explore and document the rates and patterns of ecological succession from one of the most extreme habitats in the world. The team also tested protocols for conducting sonar mapping with the new ROV as a first step towards creating high-resolution, bathymetric maps of the entire seafloor around McMurdo Station.

Where were they?Where were they?

The team was working in the waters around McMurdo Station, Antarctica. McMurdo is the largest station in Antarctica with more than 100 buildings, a harbor, landing strip and helicopter pad. More than 1000 people live and work at McMurdo Station during the austral summer!

Project VocabularyProject Vocabulary

Austral

Relating to the southern hemisphere. The austral summer is from December to February and the austral winter is from June to August.

Bathymetric Maps

Bathymetric maps show the underwater topography, including depth and contour of the bottom surface of lakes, rivers or oceans.

Benthic

Benthic organisms live on or in the bottom sediments of a sea or lake.

Ecological Succession

The more-or-less predictable and orderly changes in the composition or structure of an ecological community. For example, the recolonization of a new, unoccupied habitat created as a result of a landslide, lava flow, a forest fire etc.

Invertebrate

An animal without a spinal column, or backbone such as a worm or a snail.

Remotely Operated Vehicle (ROV)

A remotely operated vehicle is an unoccupied, maneuverable underwater robot operated by a human above the surface of the water. The ROV is linked to a human operator on land, ice, or on a ship by cables that carry electrical signals back and forth between the operator and the vehicle.

Sessile

Sessile organisms are permanently attached to a substrate and therefore not free to move around such as a barnacle.

Sonar

A method or device for detecting and locating objects by means of sound waves sent out to be reflected by the objects.
