1 Palmer LTER: understanding population variability in time and space (usually in relation to sea ice). Salp S. thompsoni Antarctic Krill E. superba

2 LTER-WAP Net community production and particle export
NCP from continuous underway Equilibration Inlet Mass Spectrometry (EIMS) determined from O2:Ar measurements R. Eveleth, N. Cassar et al (Duke Univ) in press, JGR-Oceans Thorium-234 deficit in upper ocean is an index of particle export. M. Stukel (FSU) & H. Ducklow 2015, unpub data

3 LTER-WAP Using gliders to collect spatial data on the physics and biology for the WAP continental shelf and at Palmer Station Quantifying the heat budget of the WAP requires quantifying the presence of subsurface “warm” eddies found 100’s of meters below the surface, are short-lived and spatially small (N. Couto JGR in revision) Gliders data (30,886 profiles collected) being used to define the physical regulation of phytoplankton bloom dynamics at Palmer Station (A-F, Carvalho JGR in revision) Inshore Offshore
