ABSTRACT To counteract the spread of the Covid-19 pandemic disease, the Colombian government decreed a quarantine period from March 24 to July 1, 2020, which forced the cessation of tourist activities and the closure of the main tourist destinations of the Colombian Caribbean: Santa Marta, Cartagena, and San Andrés. During this period, a significant increase in the environmental quality of these coastal zones was perceived. To quantify environmental changes in the coastal zone, the variation in chlorophyll concentration and total suspended solids observed by the Sentinel-3 satellite mission, 30 days before and after the start of the quarantine, was analyzed. The results showed a decrease in the concentration of chlorophyll (> 20 %) and suspended solids... |

Multiple year oceanographic simulations (hindcast) are identified as a priority oceanography product for fisheries and environment studies since they provide a unique continuous long-term dataset allowing integrated assessment of the ocean state and evolution. We performed a 37 year (1972–2008) hindcast run with a coupled physical–biogeochemical model in the Bay of Biscay. The coupled model and the hindcast configuration are described. A model skill assessment is performed with a large set of in-situ data. Average seasonal currents show major circulation patterns over the shelf. Among tracers, temperature and salinity have the best agreement, ahead of nitrates and silicates, chlorophyll, and finally phosphates and ammonium. For chlorophyll, improved... |
