The Argo Program has been implemented and sustained for almost two decades, as a global array of about 4000 profiling floats. provides continuous observations ocean temperature salinity versus pressure, from the sea surface to 2000 dbar. successful installation its innovative data management system arose opportunistically combination great scientific need technological innovation. Through system, fundamental physical with broad societally-valuable applications, built on cost-efficient robust...
Hydrographic time series in the northeast North Atlantic and Nordic Seas show that freshening trend of 1960s–1990s has completely reversed upper ocean. Since 1990s temperature salinity have rapidly increased Inflow from eastern subpolar gyre to Fram Strait. In 2003–2006 values reached previous maximum last observed around 1960, exceeded records. The mean properties decrease northwards, but variations seen at 57°N persist with same amplitude pattern along pathways Time correlations extreme...
The northward flow of Atlantic Water via the Barents Sea and Fram Strait is modeled, climatological volume, heat, salt fluxes into Arctic Ocean are investigated. We argue that understanding climate change in region requires knowledge mean circulation before its variability can be determined. Since estimates long‐term not available from observations, we present a modeling approach to quantify transports Norwegian Ocean. A coupled ice‐ocean model pan‐Arctic configured at 1/12° 45‐level grid...
Abstract Oceanographic observations of the Nordic Seas show significant interannual variability inflowing Atlantic Water properties and currents structure. Variations oceanic heat advected northward with influence climate. The aim study was examination, how changes West Spitsbergen Current pathways local climate conditions in Fram Strait region. Results from carried by Institute Oceanology Polish Academy Sciences summers 2000–2007 were compared time series air temperature sea ice north...
A recent study has shown increased warming in the fjords of west Spitsbergen. Their location is critical, as they are situated along main northward pathway Atlantic Water (AW) which a great source heat to Arctic Ocean and fjords. In light ongoing warming, we aim discuss differences between under transformation oceanic waters. We compared summer hydrographic conditions two located opposite ends Spistbergen: Hornsund south Kongsfjorden north. The based on high resolution CTD measurements...
Abstract We present measurements from two shipboard surveys conducted in summer 2012 that sampled the rim current system around Nordic Seas Fram Strait to Denmark Strait. The data reveal that, along a portion of western boundary Seas, East Greenland Current (EGC) has three distinct components. In addition well‐known shelfbreak branch, there is an inshore branch on continental shelf as well separate offshore shelfbreak. inner contributes significantly overall freshwater transport system, and...
Glaciers draining to the Hornsund basin (southern Spitsbergen, Svalbard) have experienced a significant retreat and mass volume loss over last decades, increasing input of freshwater into fjord. An increase in can influence fjord hydrology, hydrodynamics, sediment flux biota, especially changing climate. Here, we describe sources supply based on glaciological meteorological data from period 2006 2015. The average land bay is calculated as 2517 ± 82 Mt a−1, with main contributions glacier...
Progressive warming of the West Spitsbergen Current (WSC) has been observed since 2004. During summer 2006 temperature and salinity core Atlantic Water (AW) reached highest ever by Institute Oceanology Polish Academy Sciences (IOPAS) values. The structure WSC, heat content extent AW in Fram Strait (FS) region also changed. Temperature changes resulted from upstream Norwegian‐Atlantic (NwAC); WSC its were modified northward advection large mesoscale eddies within western branch 2005. These...
The dramatic changes in the Arctic climate observed recent years have generated an urgent need to investigate Ocean's heat budget. Mooring data and synoptic observations Fram Strait (FS) region shown that increasing amounts of been transported into Ocean (AO) times. Here we present results from conducted West Spitsbergen Current (WSC) summers 2000–2005. study was motivated by strong warm anomalies seen Atlantic Water (AW) layer over a large area WSC, WSC structure. We conclude signal only...

Abstract. The structures of the hydrographic fronts separating Atlantic-origin waters from ambient in northern Nordic Seas are discussed. Flows western and eastern branches West Spitsbergen Current create Atlantic domain borders maintain these fronts. This work is based on previous research investigations carried out project DAMOCLES (Developing Arctic Modelling Observational Capabilities for Long-term Environmental Studies). Most observational data were collected during R/V Oceania cruises....
Progressing warming in the Arctic and increased extreme weather events can significantly influence hydrography of Svalbard fjords, leading to changes towards more Atlantic-type waters fjords. In this paper, we look into hydrographic conditions Hornsund, southernmost fjord on west coast Svalbard, by analysing high-resolution CTD measurements collected July during cruises with RV Oceania between 2001 2015. These observations revealed high interannual variability temperature, salinity...
Abstract Many Arctic marine‐terminating glaciers have undergone rapid retreats in recent decades. Seasonal and year‐to‐year variations terminus position act on all tidewater glaciers, but the key controls those changes vary from region to region. Here, we examined seasonal decadal termini positions of seven inner part Hornsund, southernmost fjord Spitsbergen (Svalbard Archipelago), based a variety data 1992 2020. Combining satellite imagery, basic meteorological (air temperature, positive...
Since 1987 annual summer cruises to the Nordic Seas and Fram Strait have been conducted by IO PAN research vessel Oceania under long-term monitoring program AREX. Here we present a short description of measurements preliminary results obtained during open ocean part AREX 2016 cruise.

The longest observation record from section N along 76°30′N reveals...
Abstract Glacierised coasts undergo faster geomorphic processes than unglaciated ones. We have studied changes of the coastal area in southern Svalbard with glacier bridge between Torell Land and Sørkapp since beginning 20th century. The existence a continuous subglacial depression beneath Hornbreen–Hambergbreen system has been debated 1960s, inconclusive results. In this study we assess both topography bathymetry Hornsund Fjord Hambergbukta bay. This included ~40 km radar surveys over...

We studied overall abundance and population structure North keystone zooplankton copepod Calanus finmarchicus , which is main prey for pelagic fish some seabirds, in relation to selected environmental variables this area between 2001 2011, when warming Subarctic was particularly pronounced. Sampling within a 3‐week time window each summer...
Abstract The mechanism of glacier recession and its climatic controls are complex processes that differ across the Arctic region. Here, we investigate factors influencing front variations Hansbreen, a terminated in Hornsund fjord (SW Svalbard). We apply remote sensing data to observe fluctuations between 1992 2015 compare them atmospheric oceanographic data, sea water depth at terminus surface velocity.
