Abstract Silica is an essential element for marine life and plays a key role in the biogeochemistry of ocean. Glacial activity stimulates rock weathering, generating dissolved silica that exported to coastal areas along with meltwater. The magnitude export from large glacial such as Greenland Ice Sheet presently poorly quantified not accounted global budgets. Here we present data two fjord systems adjacent which reveal by meltwater relative other macronutrients. Upscaled entire Sheet, equals...
Greenland's ice sheet is the second largest on Earth, and under threat from a warming Arctic climate. An increase in freshwater discharge Greenland has potential to strongly influence composition of adjacent water masses with impact marine ecosystems likely be found within glaciated fjords. Here we demonstrate that physical chemical estuarine processes large Greenlandic fjord are critical factors determining fate meltwater derived nutrients particles, especially for non-conservative elements...

The study presents data from a multi-year zooplankton sampling programme with year-round monthly in sub-Arctic fjord Greenland (Godthåbsfjord). A total of 56 groups were identified over 5 years, the copepod Microsetella norvegica dominating mesozooplankton community. was found to be very abundant (maximum abundance: 408 125 ± 161 387 nauplii m−3 and 91 995 6 864 copepodites m−3) make up, on average, 87% annual assemblage. There seasonal succession whereby Cirripedia dominated biomass March...
Abstract Copepods are exposed to a high non‐predatory mortality and their decomposing carcasses act as microniches with intensified microbial activity. Sinking could thereby represent anoxic microenvironment sustaining anaerobic pathways in otherwise oxic water columns. Using non‐invasive O 2 imaging, we document that of Calanus finmarchicus had an interior even at fully air‐saturated ambient level. The extent anoxia gradually expanded decreasing levels. Concurrent sampling showed the...
Abstract Fjords form the gateway between open ocean and Greenland Ice Sheet (GIS) consequently play a crucial role for stability of Sheet. Hydrographic observations, especially with seasonal resolution, from these fjords are limited making it difficult to assess linkages fjord, coastal water masses, freshwater discharge GIS. Here we present decade‐long monthly hydrographic time series southwest fjord in direct contact Our observations reveal significant temporal spatial mass variations...
Abstract The waters on the West Greenland continental shelf and slope play an important role in global climate system with their link to subpolar North Atlantic Ocean circulation Ice Sheet. Lately, low temperature have been observed as far south ∼64°N associated a cold relatively saline water mass originating north of Davis Strait Baffin Bay referred Polar Water (BBPW). Here we use long, seasonal hydrographic time series from at study how frequently BBPW is reaching this south. analysis...
Abstract The melting of sea ice, increased terrestrial runoff and meltwater from the Greenland Ice Sheet contribute to freshening stratification Arctic seas. However, impacts on ecosystem structure carbon cycling are still poorly quantified. We studied copepod abundance, grazing, turnover in Young Sound, Northeast Greenland, during ice‐free period mid‐July early October 2014 at four stations along freshwater gradient inner fjord Sea. Freshwater enters as surface land‐terminating glaciers...
