This article analyzes the strategic importance of hydro-politics today based on the competition between big powers in the most significative strategic maritime zones, with the aim of understanding the special geographical position of Colombia, its challenges, and opportunities, as an intermediate point of connection between North and South America and with access to the Atlantic and Pacific oceans. To take advantage of its geostrategic potential, it is suggested that the country reconnects its coastline and develops a bi-oceanic connection in Choco, as a priority hydro political imperative, to stablish a strategic maritime zone which plans and develops its geostrategic power in the current international system.

The article focuses on Jeanne Villepreux-Power, a pioneering naturalist born in 1794 in France, who made contributions to the field of marine science, particularly in the study of mollusks. It mentions that she designed three types of aquariums, including the first glass aquarium used in modern aquarium keeping, which allowed her to make important observations about marine organisms, such as the species Argonauta argo.

The article focuses on multiple topics in marine science and conservation. It covers research findings on tsunamis from Antarctic glaciers, the impact of illegal fishing on sharks and CITES' role in protection, the correlation between cyclones and ocean currents, the effects of rising water temperatures on fish, the importance of marine protected areas for migratory species, fish stocks in the Northeast Atlantic, and historical sea-level rise in the Western Mediterranean.

The article provides insights into the species Serrivomer beanii, a type of eel, found in the waters near the Canary Islands, Spain. It discusses its behavior and feeding habits based on research conducted during oceanographic campaigns. It states that the species is found at varying depths, engaging in vertical migrations between deep-sea and surface waters. It highlights the need for further understanding of eel's reproductive cycle and ecological role within the region's marine ecosystem.

The article reports that Organic Chemistry has been developed fundamentally oriented to the synthesis of different compounds of industrial or pharmaceutical interest and to the extraction, purification and obtaining of products of natural origin. Topics include Nature offer organic compounds that have served for the development of numerous drugs, mainly obtained from terrestrial plants; and marine compounds of a varied nature with biological activity for use as a food supplement.

The article focuses on scientific oceanographic campaigns carried out by the ship La Bocaina to advance the knowledge of biodiversity of deep waters of the ocean Atlantic in the environment of the Canary Islands. Topics include data on two species of bathypelagic fish, Argyropelecus gigas and Argyropelecus hemygimnus as well as their bathymetric distribution; and presence of photophores capable of producing bioluminescence in the ventral region to control the changes of climate in the oceans.

The article focuses on the climatic conditions on Canary Islands in January 1979. It highlights the marine environment, orography, altitude and climatic diversity of Canary Islands. It reports on the impact of a succession of frontal systems and extratropical cyclones on rainfall and snowfall in the region.

The article focuses on Mary Sears, a pioneering oceanographer and military commander, who played a crucial role in oceanographic intelligence during military operations, especially in the context of World War II. It states that she was a trailblazer in the field of naval oceanography in the United States, gathering vital oceanographic data on tides, currents, and ocean bathymetry to aid military operations.

The article reports that WMO published its Report on the 2021 State of the Climate, which highlights that the mean sea level and the heat content trapped in the layers tops of the ocean the best marker of climate change. It mentions rainfall in the Peninsula during spring corresponded grosso way that would be statistically expected with La Niña. It also mentions drought whose persistence is marked by the Standardized Precipitation Index (SPI).

The article lists the winners of Oceans Awards 2021 including Dr. Antonio Fernández Rodríguez, Aita-Mari Humanitarian Maritime Rescue Association, and Victorio García María.
