- R/V Meteor cruise M131 from Recife to Walvis Bay, led by Peter Brandt (GEOMAR), began on October 7 2016. The cruise continues measurements carried out during the previous M130 from Mindelo to Recife, which was led by Marcus Dengler (GEOMAR). To browse the cruise reports (EN, PT, DE), please visit the PREFACE Events page.
- PIRATA FR26 survey successfully achieved. For details on the survey, click here: PIRATA-FR26 [EN]
- R/V Meteor, leg M130 was successfully carried out. To read more about this and browse the cruise reports, please visit the PREFACE Events page.
- FRV Walther Herwig III WH383 survey: as part of the analysis of the prey field dynamics of oceanic top predators in WP12, Task 12.1 and follow-up of last year’s cruise WH375 (June 12-July 20, 2014), cruise WH383 was conducted from March 2-April 24, 2015. These surveys provided information on seasonal dynamics of mesopelagic prey fishes (same stations-different seasons, WH375 as summer and WH383 as spring survey) and compare to the historical data compiled in the data base (MS38) in order to analyse long-term changes (all stations refer to historical sampling locations).

- PIRATA FR25 survey ended on April 16th 2015. For details on the survey, main achievements and where to access results, click here: [FR] or [EN]. To learn about the framework of the survey and the original plan click here.
- On the 26th of January 2015, LPAOSF (UCAD, Senegal), CRODT (ISRA, Senegal), IRD (France) and their partners, together within the Joint International Laboratory ECLAIRS (UCAD / IRD / UPMC), deployed an oceanographic and meteorological buoy “MELAX”, aimed at scientific research and operational environmental monitoring, and dedicated to the area of the Senegal-Mauritania upwelling. The buoy, unique in the sub-region, and financed by PREFACE, is equipped with oceanographic and meteorological sensors to measure short and long term changes in climate, atmosphere and marine environment. It is deployed in the heart of the Senegalese upwelling, 30km off Mbour, by 30m depth at [14 ° 20’N, 17 ° 14’W]. Read more.
- The Namibian RV Mirabilis left on its bimonthly oceanographic monitoring survey on Tuesday, 20 January. Colleagues from IOW and Hamburg University participated and the PREFACE and GENUS moorings and sediment traps on the Namibian shelf were serviced.
- The previous planned cruise with R/V Polarstern in November 2014, with the following planned cruise track: Polarstern track, was unexpectedely cancelled on short notice by the vessel operators. Next cruise details aboard R/V Meteor detailed above.
- All information on the first of three surveys undertaken for WP12 under direction of Heino Fock (TI, Germany) to be found: HERE
- 2 gliders measuring main oceanic parameters along the 14°42’ parallel between Cape Verde and Senegal (read more). Data can be accessed HERE.
- PIRATA-FR24 campaign, taking place now in the East Tropical Atlantic. This is the 24th French campaign launched through the international program PIRATA, a tripartite cooperation between the United States (NOAA), Brazil (INPE and DHN) and France (IRD and Météo-France). PIRATA is labelled […EN] […FR]
