Episode of Low Level Jets in the north and northeast coast of state of Para: a case study of 2002 april 21st to 22nd

Neste estudo descreve-se as características da estrutura vertical de um episódio de Jatos de Baixos Níveis (JBN) ocorrido no litoral do Pará, utilizando-se para tal, dados das radiossondagens de Ajuruteua, Município de Bragança coletados durante o experimento DESMATA (Impacto do Desmatamento Junto ao Litoral Atlântico da Amazônia) realizado no período de 08 a 22 de abril de 2002. Dentre os casos detectados no período chuvoso, selecionou-se um que se manteve por 12 horas com velocidade média de 15m/s e que estava direcionado de Nordeste para Leste, no ponto de máxima velocidade. Os resultados observacionais indicaram que, este JBN localizado no litoral Paraense foi resultado da ação combinada de dois fatores: (1) oscilação inercial e (2) baroclinia superficial. Estes dois fatores combinados sustentaram este JBN com intensidades entre 10 e 13m/s durante o dia e entre 14 e 16m/s durante a noite, localizado a uma altitude média de 800m acima da superfície.

Cetacean sightings around the Republic of the Maldives, April 1998

In April 1998, as part of a project to collect biopsy samples of putative pygmy blue whales (Balaenoptera musculus brevicauda) in the waters around the Republic of the Maldives, Indian Ocean, incidental sightings of cetaceans encountered were recorded. Using modified line-transect methods and handheld binoculars, a total of 267 sightings of 16 species of whales and dolphins were recorded during 20 at-sea days in the northeastern part of the atoll. Significant results include the following: (1) cetaceans were abundant and species diversity was high, including nearly every pantropical species of pelagic cetacean; (2) the spinner dolphin (Stenella longirostris) was by far the most common species encountered (56 sightings) and also had the largest mean school size ( = 50.3 individuals); (3) blue whales were rare; only four individuals were sighted; (4) a large concentration of Bryde’s whales (28 sightings in two days) was apparently feeding in nearshore waters; (5) this paper reports the first records for the Maldives of Cuvier’s beaked whale (Ziphius cavirostris), Blainville’s beaked whale (Mesoplodon densirostris) and the dwarf sperm whale (Kogia sima): the latter was particularly common (17 sightings); (6) the spotted dolphin (Stenella attenuata) was rare and almost always associated with yellowfin tuna (Thunnus albacares), spinner dolphin, or seabirds, as has been reported in the eastern Pacific and western Indian oceans.
