Antarctic krill Euphausia superba, crystal krill E. crystallorophias, and Antarctic silverfish Pleuragramma antarctica are key mid-trophic level species in the Ross Sea, connecting primary production to the upper trophic levels. Distributions of these species were constructed from observations made in the western Ross Sea from 1988 to 2004. Distributions of environmental conditions were obtained from a 5-km resolution circulation model (temperature, mixed layer depth, surface speed) and satellite-derived observations (chlorophyll, sea ice cover). A hierarchy of statistical methods determined correlations and relationships between species and environmental conditions. Each species occupies a localized habitat defined by different environmental characteristics. …

Grades: 9-12 Subjects: Biology | Life Science | Environmental Science | Chemistry
This lesson plan invites middle-school students to solve a mystery: what is ocean acidification and how is it affecting marine life in the Antarctic? To solve the mystery, students will participate in an ocean acidification scavenger hunt, and propose hypotheses and arrive at their own conclusions with interpretation of real-time data from the Antarctic.
