peregrino lander

The Peregrino Environmental Monitoring project had the general objective of assessing the fate of drill cutting discharges and their potential impact on the benthic ecosystem in the Peregrino field (licensed to Statoil), located on a shelf area off Rio de Janeiro. In a partnership with the Institute of Marine Research (IMR) and METAS (both located in Bergen, Norway), LAPS has performed the acoustic monitoring program based on time-series analysis of acoustic data collected by 38- and 120 kHz upward-looking transducers, from a benthic observatory (a so-called “Lander”). We also characterized the dynamics of sinking particles collected from three McLane sediment traps deployed in the area by image analysis of time-series samples using a FlowCAM. LAPS was in charge of a significant part of the field work in the Peregrino area, including oceanographic cruises designed to study plankton distribution for acoustic data validation, and maintenance cruises for recovery and deployment of moored instrumentation. This project was headed by Prof. Paulo Sumida and carried out in partnership with IOUSP laboratories LDB and LHICO, and funded by Statoil.
