Abstract The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to thinner and largely seasonal first-year with significant consequences for primary production. One critical challenge understand how productivity will change within the next decades. Recent studies have reported extensive phytoplankton blooms beneath ponded sea during summer, indicating that satellite-based annual production estimates may be significantly underestimated. Here we present unique...
During the N-ICE2015 drift expedition north-west of Svalbard, we observed establishment and development algal communities in first-year ice (FYI) ridges at snow-ice interface. Despite some indications being hot spots for biological activity, are under-studied largely because they complex structures that difficult to sample. Snow infiltration can grow interface when flooded. They have been commonly Antarctic, but rarely Arctic, where flooding is less common mainly due a lower snow-to-ice...
Abstract The Svalbard archipelago in the Arctic North Atlantic is experiencing rapid changes surface climate and sea ice distribution, with impacts for coupled system local society. This study utilizes observational data of air temperature (SAT) from 1980–2016 across whole archipelago, extent (SIE) operational charts to conduct a systematic assessment climatologies, long‐term regional differences. proximity warm water mass West Spitsbergen Current drives markedly warmer western coastal...
Profound changes in Arctic sea-ice, a growing desire to utilize the Arctic's abundant natural resources, and potential competitiveness of shipping routes, all provide for increased industry marine activity throughout Ocean. This is anticipated result further challenges maritime safety. Those operating ice-infested waters require various types information sea-ice iceberg hazards. Ice requirements depend on regional needs whether stakeholder wants avoid ice together, operate near or Marginal...
Abstract Climate observations inform about the past and present state of climate system. They underpin science, feed into policies for adaptation mitigation, increase awareness impacts change. The Global Observing System (GCOS), a body World Meteorological Organization (WMO), assesses maturity required observing system gives guidance its development. Essential Variables (ECVs) are central to GCOS, global community must monitor them with highest standards in form Data Records (CDR). Today,...
Abstract This review represents the Southern Ocean community’s satellite data needs for coming decade. Developed through widespread engagement and incorporating perspectives from a range of stakeholders (both research operational), it is designed as an important community-driven strategy paper that provides rationale information required future planning investment. The vast but globally connected, communities require satellite-derived in region are diverse. includes many observable...
We present a comprehensive review of the current status remotely sensed and in situ sea ice, ocean, land parameters acquired over Arctic Antarctic identify data gaps through comparison with portfolio products provided by Copernicus services. While we include several parameters, focus our is on marine sector. The analysis facilitated outputs KEPLER H2020 project. This project developed road map for to deliver an improved European capacity monitoring forecasting Polar Regions, including...
Abstract In the Arctic Ocean ice algae constitute a key ecosystem component and algal spring bloom critical event in annual production cycle. The bulk of biomass is usually found bottom few cm sea dominated by pennate diatoms attached to matrix. Here we report red tide phototrophic ciliate Mesodinium rubrum located at ice-water interface newly formed pack high early spring. These planktonic ciliates are not able attach ice. Based on observations theory fluid dynamics, propose that convection...
ABSTRACT Knowledge of Arctic sea-ice conditions is great interest for residents, as well commercial usage, and to study the effects climate change. Information gained from analysis satellite data contributes this understanding. In course using in situ combination with remotely sensed data, question how representative local scale measurements are a wider region may arise. We compare total thickness Norwegian young sea ICE expedition area north Svalbard airborne-derived electromagnetic...
