POLAR ICE

eOsphere were the coordinators for the successful POLAR ICE FP7 project (January 2014 - June 2016) focused on the economically and environmentally important Arctic and Antarctic regions. The three main POLAR ICE aims were: (1) To establish an operational sea ice information service, integrating existing national and European funded infrastructure. (2) To develop new products and services to meet known gaps. (3) To ensure POLAR ICE is driven by end users: reducing risks for shipping and offshore operators, reducing risks of environmental damage, reducing costs and providing information for climate change monitoring.

NEREIDS

The objective of the NEREIDS project was to advance the utilisation of space based technologies in the support of maritime surveillance. NEREIDS will do this by developing new tools, techniques and products that will form a part of an integrated maritime policy. Key end user groups include: fisheries, border control, maritime traffic, environment, illegal trafficking control.

eOsphere's main role in NEREIDS was to develop new algorithms to exploit SAR polarimetry for vessel detection. Over recent years satellite remote sensing using Synthetic Aperture Radar (SAR) sensors has entered a new era, with the advent of several satellites that have enhanced polarimetric capabilities as well as having improved resolutions. In general, the use of polarimetry can improve ship detection performance for a given probability of false alarms. But the extra polarimetric information will come at a cost, often the swath width that is available. Therefore it is important to have a clear understanding of the possible benefits provided by polarimetry, in order to be able to assess whether the benefits are worth the cost.

NEREIDS was led by GMV Aerospace and Defence S.A.U, Spain and is funded through the European Commission's Research Executive Agency.

Ice & foliage penetrating radar

eOsphere are currently engaged in a project (EMMA) to establish an electromagnetic scattering model of the Antarctic ice-sheets at P-band. (P-band frequencies are able to penetrate deep into the Antarctic ice sheets.) Importantly this model must be compatible with the data collected from an airborne radar ice sounder mission (POLARIS) conducted in February 2011 in Queen Maud Land and over Adelaide Island at the Antarctic Peninsula.

EMMA is being led by the Technical University of Denmark and is supported by the European Space Agency (ESA).
