Concept information
Preferred term
LTER/PAL
Definition
- Investigations at LTER Palmer site include: 1)physical forcing (solar radiation, atmospheric, oceanic and sea ice) with emphasis on ecological consequences of annual and inter-annual variation; 2) Life-history parameters of secondary producers (krill) and apex predators (penguins); 3) Biological process with emphasis on community structure and carbon fluxes (microbial, phytoplankton); 4)Physical/chemical/biological modeling that links ecosystem processes to environmental variables. Testable hypotheses link sea ice timing and magnitude to carbon and oxygen dynamics, seasonal primary production, krill abundance, distribution and recruitment; breeding success and survival of apex predators such as penguins; and large-scale interactions of the atmosphere and ocean. Sampling grids, motivated by the need for station locations that could be visited repeatedly over time scales of many years, have been established in Palmer Basin and along the west coast of the peninsula.
