The objective of this study was to make a review of the current state of knowledge on the Coastal Marine Protected Area (CMPA) Francisco Coloane in terms of the physical and chemical oceanography, the phyto-zooplankton compositions and the fish, birds and marine mammals species present, and provide temperature and salinity data collected during a marine survey carried out the 2012 fall season. Surface temperatures fluctuate between 2.0 and 9.0°C. Salinity varies between 23 and 30.9 PSU. The

In spring nutrient levels indicate low surface concentrations, except for phosphate, the phytoplankton is dominated by diatoms and the zooplankton is composed of copepods and meroplanktonic larvae with high abundance levels in the Jeronimo Channel. The family of fish most representative is the Nototheniidae, and among marine birds and mammals, the Magellan penguin and the humpback whale are the most sighted. The review indicates that it is necessary to make further studies on physical oceanography and the benthic community of CMPA.
