We investigated the recent warming of summer Atlantic Water in relation to century-long trends maximum temperature three west Spitsbergen fjords: Isfjorden, Grønfjorden and Billefjorden. On basis repeated along-fjord transects late 2003–2019, we found that has been pronounced not only outer but also inner domain where presence waters origin was registered more frequently after 2011 compared early 2000s. Furthermore, occurred bottom layers part fjord. In all fjords, year 2014 warmest saltiest...
Enhanced semidiurnal‐band velocity shear across the shelf halocline layer (SHL) was found during land‐fast ice edge mooring‐based acoustic Doppler current profiler (ADCP) and conductivity‐temperature‐depth (CTD) observations over eastern Laptev Sea (∼74°N, 128°E) in April–May 2008 April 2009. In 2008, major axis amplitude for lunar semidiurnal M 2 tidal ellipses demonstrated intermediate maximum SHL at 11–13 m (15 ± 3 cm/s), gradually decreasing to subice near‐bottom layers ∼9 cm/s (at 7 m)...
The study is based on CTD measurements collected during Arctic cruises in Isfjorden including Billefjorden and Gronfjorden summer between 2011 2017. purpose of this paper to describe the present state fjords water masses. In first part distributions masses 2014–2017 Grönfjorden 2011– 2017 are analyzed. was shown that for there were 4 types masses: surface water, intermediate transformed Atlantic water. June 2014, recorded situation when waters occupied entire area Isfjord Grönfjord....
The article briefly substantiates the need for regular monitoring of state waters Russian Arctic Seas and Basin Ocean. goals objectives hydrological conditions are formulated. General ideas about development construction a system in expressed, taking into account use modern instruments methods oceanographic observations. It is shown that most promising autonomous measuring complexes system, including moorings drifting profiler buoys. special value satellite data emphasized. No less important...
