RINCON-DIAZ, Natalia; MACAYA, Erasmo  and  GUZMAN-HENAO3, Sara E.. Contributions to the knowledge of macroalgae of the Gerlache Strait - Antarctica. Bol. Invest. Mar. Cost. [online]. 2021, vol.50, suppl.1, pp.213-220.  Epub Dec 14, 2021. ISSN 0122-9761.  https://doi.org/10.25268/bimc.invemar.2021.50.suplesp.958.

This research is a contribution to the knowledge of some marine macroalgae species collected during the “Admiral Padilla” (2016-2017) and “Admiral Campos” (2018-2019) scientific expeditions, in which the Marine and Coastal Research Institute-Invemar participated with the project “Biodiversity and Oceanographic Conditions of the Gerlache Strait-Biogerlache-Antartica”. Samples were taken using a Shipek dredge; and underwater video recordings were made with a ROV (Remote Operated Vehicle). Six (6) species were identified: four (4) Rhodophyta and two (2) Ochrophyta-Phaeophyceae. Depth and zonation information where the macroalgae were found is included, and their relationship with previous records for the study area.

Keywords : Rhodophyta; Phaeophyceae; Depth; Polar benthic macroalgae.
