Objective The MESOP 2009 cruise was part of a series of operations conducted in the Mozambique Channel with the objective of understanding the effect of mesoscale eddies on different levels of the food web (MESOBIO programme). To this end, measurements were taken inside the eddy structures to characterize the environment (hydrology, currentometry, nutrients, chlorophyll and pigments), the first trophic levels (phyto and zooplankton) and the intermediate levels (micronecton). Visual observations of seabirds and marine mammals were also made. The location of eddy structures(cyclone ' anticyclone dipole) was determined using satellite data (altimetry and ocean color mainly) and in real time on the ground by measuring currents (ADCP) and monitoring the trajectory of drifting buoys launched during the cruise. The MESOP 2009 cruise is a follow up to previous operations carried out by IRD (ECOTEM 2002-2004 programme) and by South African partners (ACEP 2007 and ASCLME 2008 programmes). The 2009 cruise was thus the continuance of the analysis of relationships between mesoscale dynamics and pelagic resources in the Mozambique Channel. For this cruise, the focus was mainly on intermediate trophic levels (zooplankton and micronecton). Its working zone corresponds to the position of the 'cyclone -anticyclone' dipole studied during the mission. The cruise fell under MESOBIO programme (Financed by WIOMSA).
