Marine Mammal: South American Research in Antarctic
Listed in NASA Earthdata CMR
This work consists of bibliographic searches on researches carried in South America in Antarctica, focusing on the Order Cetacea and Suborder Pinnipedia.
Description
The methodology was based on searching data at the site of “Periódicos Capes”, sites of universities and South American institutions, Antarctic scientific events and committees, as well as consultations in the libraries of institutes of Oceanography and Geology of the Universidade de São Paulo and the Center for Science and Health of the Universidade Federal do Rio de Janeiro.
All information was entered in a database software developed in Microsoft Access®. A total of 282 documents were obtained. Two of them (0.7%) are bachelor monographs, four (1.4%) are Master of Science dissertations, two (0.7%) are theses, 119 (42.2%) were presented as summaries in events and 155 (55%) are articles. 203 (72%) were related to species of the Suborder Pinnipedia, 65 (23%) with the order Cetacea and 14 (5%) are results of searches on cetaceans and pinipeds simultaneously.

Megaptera novaeangliae (35.5%) and Orcinus orca (12.5%) are the most studied species within the Order Cetacea. Areas of feeding in regions of bays and straits of the species M. novaeangliae and similar areas of distribution and feeding of O. orca addition of the large number of individuals in groups, leave those species most susceptible to comment and encourage the planning of research. Arctocephalus gazella (38.2%) and Mirounga leonina (37.8%) are the most studied species of Suborder Pinnipedia.
The proximity of scientific bases and the South American colonies of those species is probably responsible for such result. The Antarctic Peninsula has been a great area with the largest percentage of survey (82%). Small areas of the Antarctic Peninsula with the highest percentages of study were the Livingston (25.5%), King George (23.4%), Elephant (17.3%) islands and Gerlach Strait (10.1%).
Of the 155 articles obtained, 89 (57.4%) were published in journals with impact factor that ranges from zero to one and 51 (32.9%) with rates of impact from one to two.
