Abstract

Highlights

The Arctic cryosphere is transforming rapidly in response to recent climate change
Land-derived meltwater can affect primary production far away from the coastal zone (Arrigo et al 2017), while waters transported by large-scale current systems have an influence on the hydrography of some coastal systems (Sejr et al 2017)
There is a need for closer cooperation between different proxy specialists and for critical assessment of the current analytical, numerical, and ecological knowledge

Summary

Introduction

The Arctic cryosphere is transforming rapidly in response to recent climate change. Accelerated melt of glaciers, ice caps and the Greenland ice sheet, increased glacial runoff, diminishing sea-ice extent and volume, coastal erosion, and permafrost thaw all have profound impacts on Arctic coastal environments (Fig. 1). Recent studies show that the impacts of land-derived freshwater on coastal circulation and contributions of dissolved and particulate matter are heavily dependent on the marine system, and have a non-linear impact on primary productivity (Hopwood et al 2018). Land-derived meltwater can affect primary production far away from the coastal zone (Arrigo et al 2017), while waters transported by large-scale current systems have an influence on the hydrography of some coastal systems (Sejr et al 2017).
