Four major functional units have been identified in the Southern Ocean and the mechanisms
that control the dynamics of nutrients and phytoplankton are detailed for the different sub …

The West Antarctic Peninsula (WAP) has experienced significant change over the last 50
years. Using a 24 year spatial time series collected by the Palmer Long Term Ecological …

In January–February 1999, we performed shipboard iron-and macronutrient-addition
experiments in the Crozet Basin, Indian sector of the Subantarctic Southern Ocean, to …

Primary production events in both the Arctic and the Antarctic are highly localized. Carbon-
14 incubations that did not account for this caused antarctic primary production estimates to …

Summary A large percentage (> 50%) of total chlorophyll found in waters surrounding
Antarctica is contained in the pico-and nano-plankton (< 20 μ m) size-fraction. About 30% of …

An ecological model to calculate phytoplankton development and microbial loop dynamics
in the marginal ice zone of the antarctic ecosystem has been established on the basis of …

Phytoplankton dynamics in the region of 55–70° S, 170° W were investigated using Sea-
viewing Wide Field-of-View Sensor satellite imagery, shipboard sampling and experimental …

The extent, duration, and seasonality of sea ice and glacial discharge strongly influence
Antarctic marine ecosystems. Most organisms' life cycles in this region are attuned to ice …

The Pahner Long-Term Ecological Research (LTER) area, the area west of the Antarctic
Peninsula, is an important oompmml r: l the Antarctic marine CCOIystem which iJ composed …

Ocean Station Papa (OSP, 50° N 145° W) in the NE subarctic Pacific is characterised as
high nitrate low chlorophyll (HNLC). However, little is known about the spatial extent of these …
