Size structure and sedimentation of biogenic microparticulates in a subarctic ecosystem

Paul K. Bienfang

The Oceanic Institute Makapuu Point, Waimanalo, HI 96795, USA

Received on March 1, 1984; accepted on July 1, 1984 Data describing sinking rates and size structure of microparticulate material were collected from Resurrection Bay, Alaska during the summer. Spring conditions were inferred from similar data obtained from a large outdoor pond supplied with nutrient-rich deep water. Size structure of chlorophyll and photosynthesis were clearly different in the two assemblages. In the summer assemblage, the majority of particulate chlorophyll, carbon, phosphorus, nitrogen, silica, and photosynthesis occurred in the <5 µm fraction. Average sinking rates of the various constituents of the total suspended material differed substantially and ranged from 0.07 to 0.63 m d–1. The total downward flux of carbon was l3% of daily primary production and the sinking of material greater than 20 µm accounted for nearly all of the downward flux. Sinking rates of actively growing spring assemblages differed from the smaller summer assemblages by only a few tenths of a meter per day.
