EISPAC

Effects of ice stressors and pollutants on the Arctic marine cryosphere

Overview

Twitter: @CAO_EISPAC

Chemical contaminants and plastic debris appear to accumulate in sea ice. In a warmer Arctic the behaviour of these pollutants in single season ice and the timing and extent of exposure for ice-associated biota is unknown but will be investigated.

  • Atmosphere or ocean? – where do chemicals and plastics present in sea ice come from and can we measure the exposure to ice-associated organisms?
  • Is ice melt critical to the delivery of both nutrients and contaminants to marine surface waters, especially during the Arctic spring when biological activity in the surface ocean increases?

The aim of EISPAC is to assess the importance of ice–associated pollutants and nutrients on ice habitat functioning.

This project is co-funded by the German Federal Ministry of Education and Research and by NERC.

Dr Crispin Halsall, Lead Investigator of EISPAC:

“Chemical pollutants and plastic debris are present in the Arctic Ocean and can become entrained in sea ice. The changing nature of sea ice, with earlier and erratic periods of thaw, could be altering the processing and release of pollutants alongside key nutrients, which in turn affects biota at the base of the marine foodweb. EISPAC provides a unique opportunity to explore these issues by bringing UK and German researchers together to participate in field and laboratory projects to investigate contaminant and nutrient fate in the sea ice system”

Lead Investigators

  • Dr Crispin Halsall

    Co-lead investigator, Lancaster University

    Crispin Halsall is a Reader in environmental organic chemistry at Lancaster Environment Centre (LEC), Lancaster University. His research expertise is in investigating the environmental fate and impact of synthetic organic chemicals, particularly persistent organic pollutants. Crispin is the co-lead investigator of EISPAC and will investigate the fate of organic pollutants in the sea ice system through both field and laboratory-based studies.
