Temperature, light and dissolved nutrients are considered the “master” properties controlling
primary production in the ocean. Each of these properties, in turn, is influenced by water …

There is strong evidence of an increase in primary production (PP) in the Arctic Ocean (AO)
over the last two decades. Further increases will depend on the interplay between …

Polar regions are poorly understood components of global biogeochemical cycles. This
paper discusses the influences of nitrate and ammonium concentrations on nitrate uptake …

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 …

Abstract During the International Polar Year (IPY), large international research programs
provided a unique opportunity for assessing the current state and trends in major …

Many terrestrial and freshwater ecosystems and their component ecological units in the
Antarctic and Sub-Antarctic have been characterized in terms of single sets of chemical data …

The standing stock of pelagic primary producers is conveniently expressed as the difference
between growth and reduction of the standing stock by grazing or by sinking out of the …

Oceanic high‐nutrient, low‐chlorophyll waters are characterized principally by the
persistence of major nutrients at the sea surface. This condition indicates control of …

Phytoplankton biomass (chlorophyll a) and primary production rates in Baffin Bay during
summer 1978 were comparable to levels reported for other open water arctic and subarctic …

Studies in a large (30000 km2) sampling grid around Elephant Island, Antarctica, during
January–March of four successive years (1990–1993) have shown that one of the water …
