An assessment of key model parametric uncertainties in projections of Greenland Ice Sheet behavior [PDF]

, 2012
Lack of knowledge about the values of ice sheet model input parameters introduces substantial uncertainty into projections of Greenland Ice Sheet contributions to future sea level rise.

Regime shift in sea-ice characteristics and impact on the spring bloom in the Baltic Sea

Oceanologia, 2022
We evaluated the temporal and spatial trends of the hydrological (temperature and sea ice) and biochemical (chlorophyll-a concentration) characteristics in springtime in the Baltic Sea.

Comparison between a multi-variate nudging method and the ensemble Kalman filter for sea-ice data assimilation

Journal of Glaciology, 2018
Increasing ship traffic and human activity in the Arctic has led to a growing demand for accurate Arctic weather forecast. High-quality forecasts obtained by models are dependent on accurate initial states achieved by assimilation of observations.

Improving interpretation of sea-level projections through a machine-learning-based local explanation approach [PDF]

The Cryosphere, 2022
Process-based projections of the sea-level contribution from land ice components are often obtained from simulations using a complex chain of numerical models.

Assimilation of sea ice motion in a finite‐element sea ice model [PDF]

Journal of Geophysical Research: Oceans, 2009
A finite‐element sea ice model (FESIM) is applied in a data assimilation study with the singular evolutive interpolated Kalman (SEIK) filter. The model has been configured for a regional Arctic domain and is forced with a combination of daily NCEP reanalysis data for 2‐m air temperature and 10‐m winds with monthly mean humidities from the ECMWF ...

Evaluation of Operation IceBridge quick-look snow depth estimates on sea ice [PDF]

, 2015
We evaluate Operation IceBridge (OIB) ‘quick-look’ (QL) snow depth on sea ice retrievals using in situ measurements taken over immobile first-year ice (FYI) and multi-year ice (MYI) during March of 2014. Good agreement was found over undeformed FYI (-4.5

Observations and modelling of first-year ice growth and simultaneous second-year ice ablation in the Prydz Bay, East Antarctica

Annals of Glaciology, 2017
The seasonal cycle of fast ice thickness in Prydz Bay, East Antarctica, was observed between March and December 2012. In March, we observed a 0.16 m thickness gain of 0.22 m-thick first-year ice (FYI), while 1.16 m-thick second-year ice (SYI) nearby ...

Recent trends in melting conditions on the Antarctic Peninsula and their implications for ice-sheet mass balance and sea level [PDF]

, 2006
Long-term records from meteorological stations on the Antarctic Peninsula show strong rising trends in the annual duration of melting conditions. In each case, the trend is statistically significant and represents a major increase in the potential for ...

A suite of coupled ocean-sea ice simulations examining the effect of regime shift in sea-ice thickness distribution on ice–ocean interaction in the Arctic Ocean [PDF]

Geoscientific Model Development
A major shift in Arctic sea ice occurred in 2007, transitioning from thicker, deformed ice to thinner, more uniform ice with reduced surface roughness. This abrupt change likely altered the dynamic and thermodynamic interactions between sea ice and ocean,
