Última Preliminary assessment of the impact of Hurricane Iota on coral reefs in Providencia and Santa Catalina Islands Boletín de Investigaciones Gómez,Carlos E.; Millán,Santiago; Acosta-Chaparro,Andrés; Abril-Howard,Alfredo; Navas-Camacho,Raúl. ABSTRACT Hurricanes are important natural destructive forces for coral reefs that can change the structural component of the habitat. On November 16th, 2020, the hurricane Iota passed ~10 km north of the islands of Providencia and Santa Catalina with sustained winds of a category 5 hurricane. The purpose of this study was to document the magnitude of the impact on coral reefs around the islands two weeks after the hit, as part of the “Operación Cangrejo Negro”. Visual assessments were performed at 11 representative coral reef formations between 2 and 17 m depth. Estimates of the impact were evaluated within an approximate area of 200 m2, which was categorized with score values ranging from 0 to 5 according to the level of damage. Preliminary estimates at...

ABSTRACT Seagrass meadows have stood out for being very effective fixing atmospheric carbon, among others, due to their ability to produce plant biomass. Therefore, the values of shoot density (m2), biomass (cores) and carbon present in 12 locations with Thalassia testudinum at the Colombian Caribbean (La Guajira and San Andrés Island) were quantified. The biological samples were processed in laboratory until obtaining the values of aerial, underground and total dry weight, and the estimation of the carbon was stablishing from a ratio of 35 % of the dry biomass. Statistical tests were carried out to determine significant differences between the sites, highlighting the aerial biomass in La Guajira and the underground biomass in San Andrés. It was calculated... Tipo: Info:eu-repo/semantics/article Palavras-chave: Seagrass; Colombia; Biomass; Blue carbon..
