Abstract. Fram Strait is the main gateway for sea ice export out of Arctic Ocean, and therefore observations there give insight into composition properties in general how it varies over time. A data set ground-based airborne electromagnetic thickness measurements collected during summer between 2001 2012 presented here, including long transects well southern part Transpolar Drift obtained using fixed-wing aircrafts. The primary source surveyed leaving Laptev Sea its age has decreased from 3...
Abstract Along with changes in sea ice extent, thickness, and drift speed, Arctic regime is characterized by a decrease of fast season reduction extent. The most extensive cover the develops southeastern Laptev Sea. Using weekly operational charts produced Antarctic Research Institute (AARI, Russia) from 1999 to 2013, we identified five main key events that characterize annual evolution Linking occurrence atmospheric forcing, bathymetry, freezeup, melt onset, examined processes driving...
The cryosphere plays a critical role in Central Asia, particularly terms of water availability for agriculture and energy production via hydropower stations. Glaciers serve as essential sources both seasonal long-term supply, while snow storage mountainous regions significantly influences availability. Consequently, the accurate estimation resources stored glaciers is vital effective management transboundary resources. However, limitations data pose significant challenges to comprehensive...
Abstract. This study explores a link between the long-term variations in integral sea ice volume (SIV) Greenland Sea and oceanic processes. Using Pan-Arctic Ice Ocean Modeling Assimilation System (PIOMAS, 1979–2016), we show that increasing flux through Fram Strait goes parallel with decrease SIV Sea. The overall loss is 113 km3 per decade, while total import increases by 115 decade. An analysis of ocean temperature mixed-layer depth (MLD) over climatic mean area winter marginal zone (MIZ)...
Accurate representation of fast ice in numerical models is important for realistic simulation numerous sea-ice and ocean variables. In order to simulate seasonal interannual variability fast-ice extent, the mechanisms controlling development need be thoroughly understood. The objective this paper investigate contributing advance edge its winter location south-eastern Laptev Sea. study based on time series synthetic aperture radar (SAR) imagery 2007/08 2009/10. A detailed examination...
For regional environmental studies it is important to know the location of fast ice edge which affects coastal processes in Arctic. The aim this study develop a new automated method for delineation from SAR imagery. based on fine resolution hybrid sea tracking algorithm utilizing advantages feature and cross-correlation approaches. developed consists three main steps: drift field retrieval at sub-kilometer scale, selection motionless features delineation. was tested time series C-band...
Abstract. This study explores a link between the long-term variations in integral sea ice volume (SIV) Greenland Sea and oceanic processes. Using Pan-Arctic Ice Ocean Modelling Assimilation System (PIOMAS, 1979–2016), we show that negative tendencies SIV go parallel with increasing flux through Fram Strait. The overall loss comprises 113 km3 per decade, while total import strait is by 115 decade. An analysis of ocean temperature mixed layer depth (MLD) marginal zone (MIZ), based on ARMOR...

An extensive data set ground-based airborne electromagnetic thickness measurements collected between 2001 2012 presented here, including long transects well southern part Transpolar Drift obtained using fixed-wing aircrafts.

Droughts pose significant challenges to water resources, agriculture, and socioeconomic stability, particularly in regions susceptible climatic extremes such as Central Asia (CA) with its complex topography diverse ecosystem. In the past several years there has been a substantial decrease storage region which further could lead instability. Water is mainly used for irrigation hydropower production region. CA, availability of ground observations restricted, most measurement stations being...
The Obskay guba Bay is a region of rapidly developing oil and gas exploration. Knowing the current sea ice conditions including dangerous phenomena e. g. ridges stamukhas important for safety coastal underwater construction as well ecological risk assessment. With this study, we aim to obtain new data on seasonal cycle in southern central part 10 years (from 2007 2017) demonstrate capacity satellite obtaining varying characteristics region. Analyzing daily visual MODIS available Sentinel-1...
Abstract Using operational sea-ice maps, we provide first insight into the seasonal evolution of fast ice in East Siberian Sea for period between 1999 and 2021. The season tends to start later by 4.7 d per decade end earlier 9.7 decade. As a result, there is trend towards shorter length 2 weeks analysis air temperatures indicates that onset are largely driven thermodynamic processes. Two spatial modes (large, L-mode small, S-mode) cover which have significant areal differences were...
