2009 is the third-lowest Arctic sea ice extent observed, consecutively to the 2007 and 2008 minima
Ifremer has been monitoring coastal waters from space for many years using SST, chlorophyll and turbidity levels derived from satellite observations, as a contribution to several European environmental monitoring frameworks. We are in particular committed to provide rapid alert in case of eutrophication or HAB (Harmful Algal Bloom) occurring in areas under our responsability. The exceptional bloom of karenia mikimotoi that took place in July 2010 in the Channel is such an example of an early detection which emphasizes the benefit of using satellite observation as a support to coastal environment monitoring.
This summer, sea ice extent is lower than the 2005 minimum extent (the second-lowest extent observed).
On the afternoon of the 5th January 2008, a team of adventurous surfers was able to ride huge waves at Cortes Bank spot, bringing back these impressive reports and pictures of some of the biggest waves ever surfed on this spot. But swells can be observed and followed also from space using the synthetic aperture radars such as the ASAR instrument onboard ENVISAT on a routine basis. We provide every day animations of the latest observed swell systems over the world and this exceptionnal event reveals how "local" observation and spaceborn remote-sensing can impressively match together.
Radiometers onboard satellites are commonly used to estimate sea ice concentration and extent. For several years, CERSAT has been providing daily Arctic sea ice maps at 12.5 km resolution.
The month of September of this International Polar Year is marked by a record : Arctic sea ice has hit its lowest value since the beginning of satellite observations exist (almost 30 years).
We are pleased to offer the following announcement from ESA : the European Space Agency is organising its second SAR oceanography workshop, SEASAR 2008, entitled "Advances in SAR Oceanography from ENVISAT and ERS missions", which will be hosted at ESA ESRIN in Frascati, Italy, from 21 to 25 January 2008. This workshop will focus on all ocean applications of SAR, including remote-sensing of wind, waves, currents and oil-spill, operational applications and services, etc...
Four years after a first meeting to assess the state of knowledge on waves in relation to currents, surface drifts and air-sea interactions, SHOM and Ifremer will reconvene a workshop on this topic in Brest, on 19th September 2007. Our purpose is to track recent progress in the understanding of wave-current interaction processes in relation with the operational forecasting systems. Please read the full annoucement for this workshop.
Registrations are now closed, thank you to the numerous participants and see you in Brest!
