Three new species of agathotanaids belonging to the genera Agathotanais, Bunburia and Paranarthrura are described. The descriptions were based on material collected from southwestern Java, Indonesia, Indian Ocean during the research cruise SJADES in 2018. The specimens were obtained using a box corer from lower bathyal depths of 836–2,355 m. These three genera are recorded from Southeast Asia for the first time.

O objetivo deste trabalho foi a caracterização geotécnica de 12 amostras indeformadas coletadas na porção submersa da Praia do Cassino, sul do Rio Grande do Sul. A campanha de amostragem é oriunda do projeto “Programa de Monitoramento do Sítio de Despejo e Área Adjacente do Material Dragado do Canal de Acesso ao Porto de Rio Grande” coordenado pelo Laboratório de Oceanografia Geológica - LOG do Instituto de Oceanografia e conta com participação do Laboratório de Engenharia Costeira - LEC da Escola de Engenharia da Universidade Federal do Rio Grande – FURG. As amostras foram coletadas com o auxílio de amostrador do tipo Box Corer com cota batimétrica entre 8 e 10,5m. Os resultados obtidos em cada ponto foram descritos através de ensaios de caracterização básica objetivando a determinação da curva granulométrica, pelo método de sedimentação e peneiramento, determinação dos limites de Atterberg e determinação dos índices físicos. A análise granulométrica indicou solos finos classificados pelo diagrama de Shepard (1954) como argila siltosa, com exceção de um ponto, classificado como argila arenosa. Os valores de limites de consistência juntamente com a distribuição granulométrica, foram utilizados para determinar a classificação geotécnica dos solos pela metodologia SUCS. Este método classificou os solos estudados como argilas muito plásticas e argilas siltes orgânicos ou siltes altamente plásticos. Os resultados encontrados corroboram os dados encontrados na literatura.

Marine geological survey of Ekspedisi Widya Nusantara (EWIN) LIPI 2016 was conducted by using RV Baruna Jaya VIII in the Sumba Waters from 4 to 26 August 2016. One of the aim of this survey is to understand the sea floor surface sediment characteristics and its influence to the benthic foraminifera distribution. Seven sediment samples were collected from sea floor surface in Sumba Strait, at the different location and depth using grabbing method with box corer. The samples have analyzed for the foraminifera content, sediment grain size, organic matter and carbonate content, and chemical element by XRF method. The living benthic foraminifera distribution increase to the east of the research area, which have higher content of the organic material and Fe, Rb, Zr, Zn and Sr elements in the sediment. The benthic foraminifera distribution most abundance founded at the depth of 800-1000 m with sediment types are sandy coarse silt  to sandy very coarse silt.Keywords: Benthic foraminifera, distribution, sea floor sediment, Sumba Strait.

During the INDEMARES/CHICA 0610, 0211 and 0412 expeditions, carried out in the northern Spanish sector of the Gulf of Cádiz (Spain), samples were collected with a box-corer in 11 mud volcanoes and their adjacent bottoms. Chemoautotrophic communities were found in nine mud volcanoes. Among Decapoda, a rare eucalliacid, belonging to the genus Calliax and related to the Mediterranean infralittoral speciesC. lobata(de Gaillande and Lagardère 1966), was present in three of them. Data on its morphology, biogeographic distribution, vertical distribution within the burrows, sediment composition, pH and redox potential values (each in 5 cm intervals) are given; information on the chemoautotrophic communities associated with this species are also provided.
