Ratios of Si, C and N uptake by microplankton in the Southern Ocean

Autor: Mary-Lynn Dickson, Raymond N. Sambrotto, Mark A. Brzezinski, David M. Nelson

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 50:619-633

Nutrient uptake ratios and the Si:C:N composition ratios of particulate matter were measured within a diatom bloom located between the Antarctic Polar Front and the edge of the receding pack ice in the Pacific sector of the Southern Ocean along 170°

During the 1996–1998 Antarctic Environment and Southern Ocean Process Study (AESOPS), a component of US JGOFS, we obtained seasonal or longer-term data sets on the rates of production, vertical transport, remineralization and burial of particulate

Oxygen production and respiration in the Antarctic Polar Front region during the austral spring and summer

Autor: Mary-Lynn Dickson, Joseph Orchardo

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 48:4101-4126

Gross and net O2 production and dark community respiration rates were measured during austral spring and summer from 53°S to 70°S along 170°W across the Antarctic Polar Front (APF). Integrated production and respiration rates were compared for sta

Production and respiration rates in the Arabian Sea during the 1995 Northeast and Southwest Monsoons

Autor: James J. McCarthy, Raymond N. Sambrotto, J Orchardo, Richard T. Barber, Mary-Lynn Dickson, John Marra

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 48:1199-1230

In this paper we examine the relationships among oxygen, carbon and nitrogen production and respiration rate measurements made in the Arabian Sea during the 1995 Northeast (NEM) and Southwest (SWM) Monsoons. Increased biological production characteri

Plankton community composition, production, and respiration in relation to dissolved inorganic carbon on the West Florida Shelf, April 1996

Autor: Gabriel A. Vargo, Gary L. Hitchcock, Mary-Lynn Dickson

Publikováno v: Journal of Geophysical Research: Oceans. 105:6579-6589

In April 1996 the Florida Shelf Lagrangian Experiment examined dissolved inorganic carbon (DIC) dynamics on the West Florida Shelf. DIC concentrations increased over 2 weeks at an average rate of 1 μmol kg−1 d−1 in a patch of the intentionally r

Constraining bacterial production, conversion efficiency and respiration in the Ross Sea, Antarctica, January–February, 1997

Autor: Joe Orchardo, Mary-Lynn Dickson, Farooq Azam, Hugh W. Ducklow, David L. Kirchman, Grieg F. Steward, John Marra

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 47:3227-3247

Bacteria consume dissolved organic carbon at rates averaging about 50% of primary production across a wide spectrum of marine ecosystems. However, total utilization rates are poorly constrained due to a lack of data on conversion e$ciencies and/or ba

Net and gross production in the Ross Sea as determined by incubation experiments and dissolved O2 studies

Autor: Michael L. Bender, J Orchardo, Mary-Lynn Dickson

Publikováno v: Deep Sea Research Part II: Topical Studies in Oceanography. 47:3141-3158

We report net and gross production rates for samples from three JGOFS cruises to the Ross Sea during spring–autumn 1996–1997. We summarize continuous electrode measurements of mixed-layer O2 supersaturation taken during January 1997, and use thes
