Variations in hydrography, nutrients and chlorophyll a in the marginal ice-zone and the central Barents Sea

TL;DR: In this paper, the authors investigated the topography, water masses and climate change in the central Barents Sea and found that the phytoplankton biomass was concentrated in the upper 30 m in the strongly stratified MIZ, and that new production rates were closely related to the mixing depth with highest rates in the deeper mixed Atlantic region and trenches where the Polar Front was located.

Seasonal variation in vertical flux of biogenic matter in the marginal ice zone and the central Barents Sea

TL;DR: In this paper, the spatial and seasonal variations in the vertical flux of particulate biogenic matter were investigated in the Barents Sea in winter and spring 1998 and summer 1999, where an array of simple cylindrical sediment traps were moored for 24 h between 30 and 200 m along a transect from the ice-free Atlantic water to Arctic water with up to 80% ice cover.

Seasonal and spatial changes in biomass, structure, and development progress of the zooplankton community in the Barents Sea
TL;DR: In this article, seasonal and regional variations in biomass and vertical distribution of mesozooplankton as well as cohort development in Calanus spp. were investigated along a transect across the central Barents Sea and marginal ice zone.

Vertical export of particulate organic carbon: Attenuation, composition and loss rates in the northern Barents Sea
TL;DR: In this article, short-term sediment trap deployments at 6-8 depths from 20 to 200m were conducted to evaluate the driving forces influencing changes in quantity and composition of vertical flux with depth and environmental conditions in ice-covered waters.

Seasonal variation in production, retention and export of zooplankton faecal pellets in the marginal ice zone and central Barents Sea
TL;DR: In this article, the vertical distribution and sedimentation of faecal pellets as well as the production rates of FPs by larger copepods were studied during three cruises to the Barents Sea in March and May 1998, and July 1999.
