Abstract

A study of the variation in sea ice algal distribution and production was performed during June and early July 1999 in Young Sound, northeastern Greenland, Measurements were performed in situ by divers using an underwater pulse-amplitude-modulated (PAM) fluorometer, oxygen microelectrodes and C-14 incubations. In early June, Young Sound. was covered by similar to1.6 m of sea ice and similar to30 cm of dry snow, which reflected similar to75% of the incident light. These conditions resulted in low irradiance below the sea ice (<2 mumol photons m(-2), s(-1)), low values of chlorophyll a (
