Book excerpt: This report is a continuation of the current observational program and presents data on ice thickness during the 1960-61 and 1961-62 seasons. The network has been expanded to Alaska during this period and some station changes have taken place. These changes are discussed and some supplemental ice thickness data for two stations on the east coast of Greenland are presented. The data are presented in their original form in order to make them fully available to potential users. Analysis has been limited to a study of maximum ice thicknesses. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 180. This volume addresses the rapid decline of Arctic sea ice, placing recent sea ice decline in the context of past observations, climate model simulations and projections, and simple models of the climate sensitivity of sea ice. Highlights of the work presented here include An appraisal of the role played by wind forcing in driving the decline; A reconstruction of Arctic sea ice conditions prior to human observations, based on proxy data from sediments; A modeling approach for assessing the impact of sea ice decline on polar bears, used as input to the U.S. Fish and Wildlife Service's decision to list the polar bear as a threatened species under the Endangered Species Act; Contrasting studies on the existence of a "tipping point," beyond which Arctic sea ice decline will become (or has already become) irreversible, including an examination of the role of the small ice cap instability in global warming simulations; A significant summertime atmospheric response to sea ice reduction in an atmospheric general circulation model, suggesting a positive feedback and the potential for short-term climate prediction. The book will be of interest to researchers attempting to understand the recent behavior of Arctic sea ice, model projections of future sea ice loss, and the consequences of sea ice loss for the natural and human systems of the Arctic.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic sea ice cover is strongly connected to the global climate system and therefore not only subject to internal variability but also in a phase of significant change related to the ongoing increase in global mean surface temperatures. The most important parameters to monitor and describe sea ice are its areal extent, thickness, and motion. While reliable, long-term satellite measurements of sea ice concentration, which is used to derive the area covered by sea ice, exist since the late 1970s, sea ice thickness and motion data sets of comparable quality and length are currently not available. The overarching goal of this dissertation is to contribute to the improvement of sea ice thickness observations and to understand and quantify the impact of ongoing sea ice thickness changes and variability in the most important regions of sea ice formation on the overall Arctic sea ice budget. To achieve that, the first study presented in this dissertation focuses on extending the knowledge about sea ice thickness variability in the Laptev Sea by developing a new method to derive sea ice thickness time series from moored sonars. It is shown that daily mean sea ice thickness time series can be inferred from basic, moored upward-looking Acoustic Doppler Current Profilers. This adaptive approach allows to revisit data sets from past mooring deployments in the Laptev Sea and exploit them to extend the available sea ice thickness records and close observational gaps in a region that, due to its limited accessibility, is vastly under-sampled. These new data sets are the basis for the validation of multiple satellite sea ice thickness products, including the longest available one introduced by the European Space Agency, which provides Arctic-wide sea ice thickness since 2002. It is shown that in the first-year ice dominated Laptev Sea the investigated satellite products provide the most frequently occurring (modal) rather than the mean sea ice thickness. This important discovery allows for a better interpretation of the available satellite records, especially for the investigation of sea ice volume transports, and underlines their deficiencies in representing dynamically deformed sea ice. Based on the knowledge gained in the Laptev Sea, the final study presented in this dissertation follows the Arctic sea ice life cycle from the regions of ice formation along the Transpolar Drift towards Fram Strait and analyses whether sea ice thickness anomalies induced in the source regions of Arctic sea ice propagate to the central Arctic Ocean and beyond. More specifically, it is investigated which particular processes are potentially responsible for the induced anomalies in the source regions and whether their signals persist until the end of the Transpolar Drift. In the absence of a single-source Arctic-wide, high temporal and spatial resolution sea ice thickness data product, this final part promotes the combination of different techniques and tools for the investigation of this complex Arctic climate parameter. At the center of the investigation is an extended long-term electromagnetic induction sounding-based sea ice thickness time series, which shows a general thinning and decreasing age of sea ice at the end of the Transpolar Drift between 2001 and 2020. Due to its length, this unique time series also permits to put ice thickness measurements conducted during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition into the historical context. Lagrangian ice tracking and modelling of thermodynamic sea ice growth along the pathways of Arctic sea ice reveal a potential preconditioning effect of observed increases in upward ocean heat fluxes in the eastern Arctic, termed Atlantification, that decelerates sea ice growth. The presented efforts are an important contribution to the better understanding of Arctic sea ice thickness variability and change and can be seen as starting points for more targeted analyses of the driving mechanisms behind them. In addition, the acquisition, validation, and extension of sea ice thickness observations provide the basis for more detailed sea ice modelling, which will improve not only the monitoring but also the prediction of Arctic sea ice thickness changes in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Sea-ice surface temperatures observed at Eureka, N.W.T., Canada, during 1949-50 and 1950-51 were used to compute the numerical value of the expression k/L rho, where k = thermal conductivity, L = latent heat of fusion and rho = density. The numerical value for these combined physical properties of sea ice was found to increase from approximately 0.000047 to 0.00007 during ice growth (between 6 November and 22 December) from 0.6 to 1 m thickness. During the increase from 1.1 to 1.3 m (between 20 January and 10 February) the value of k/L rho ranged from 0.00007 to 0.00008 and then decreased slightly during the rest of the growth period. These variations in the value of k/L rho throughout the winter season were considered as changes in the effective conductivity caused by physical changes and distribution of brine in the sea ice. Since no observations on sea-ice salinity were made at Eureka, it was not possible to investigate the effect of the physical properties separately. A study on the relation between sea-ice accretion and temperature gradient disclosed a correlation coefficient of r = 0.73. (Author).

This book was released on 2017-04-24 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science. The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.
