Assessment of Primary Production in the Bering with New Approach
2014
Kivva, K.K.
Oceanographic surveys of high spatial resolution were carried out in the western Bering Sea during past few years, which allow estimating primary production in the region based on drawdowns of nutrients . Present work suggests a new method of net (≈ to new) and gross (≈ to total) primary production assessment based on summer or autumn nutrients and dissolved oxygen profiles . For 2012, gross (or total) primary production in the region was in range of 50–250 g C m–2 a–1, while net community (or new) primary production reached 30–80 g C m–2 a–1 . New to total production ratio was in a range of 0 .2–0 .8 . The presented new method revealed good agreement with previous studies and supposed for use in the future investigations
