📋 Tender Overview
The research allowed us to understand the environmental and oceanographic conditions that influence the marine ecosystem and the artisanal fishing activity in the area.
Specialists from the Institute of the Sea of Peru (IMARPE) carried out a study of the oceanographic profile in front of the bay of the port of Huacho with the purpose of evaluating the current state of the marine environment and understanding the dynamics of the water masses that influence the productivity and fishing activities of this important coastal area.
The research was carried out along 10 nautical miles from the coast, reaching depths of up to 100 meters. During the field work, water samples were collected to analyze variables such as temperature, salinity, dissolved oxygen, pH and nutrients, fundamental parameters to understand the health and functioning of the marine ecosystem.
During the study, the presence of mixing waters resulting from the interaction between Cold Coastal Waters (CWA) and Subtropical Surface Waters (SSA) was recorded. Temperatures of 22.22 degC on the surface and 17.8 degC at 100 m depth were evident in the most oceanic station and slight variations in salinity within the evaluated area. Likewise, pH records showed a decreasing trend with depth. The lowest concentrations of dissolved oxygen were detected particularly at levels far from the surface, a condition associated with the persistent upwelling processes induced by the action of local winds.
This type of research allows us to strengthen scientific knowledge about the Peruvian sea and provides key information to evaluate the approach to the warm water coast, the sustainable management of fishing resources, contributing to the conservation of marine ecosystems and the development of activities that depend on them.
