Situada na Cidade de Camaçari – Bahia, entre a Praia de Guarajuba (0602065 L/ 8601950 N) e a Praia do Forte (0604936 L / 8606730 N), a Praia de Itacimirim, até a década de 60, era considerada uma pacata vila de pescadores. Com a criação do Polo Petroquímico, nos anos 70, Camaçari passou a representar o carro chefe da política de desenvolvimento ind...
Seismic oceanography comes as a tool for obtaining thermohaline data using data from the petroleum industry. During seismic processing for the entire oil industry seismic data corresponding to the water column is discarded which corresponds to approximately 25%. of the total data. Seismic processing to obtain thermohaline or oceanic structures conv...
A Baía de Todos os Santos (BTS) está inserida dentro do contexto geológico da Bacia do Recôncavo, sendo receptor natural dos sedimentos terrígenos desta Bacia e produtor de carbonatos. Sua profundidade máxima é de-60 metros, sendo as maiores localizadas em canais incisos, que são atribuídos aos períodos de maiores variações eustáticas do nível rela...
Elongate, rock-framed Santa Catarina Island partly encloses a low-energy marine embayment that communicates with the ocean via narrow, rock-bounded inlets with ebb and flood-tide deltas. The bay shoreline consists of low-energy sandy beaches, strandplains, mangroves and bayhead deltas while the exposed Atlantic shoreline comprises a series of headl...
The inner continental shelf (0–50 m water depth) off Santa Catarina, southern Brazil was investigated using seismic stratigraphic methods to identify and interpret the major seismic stratigraphic units and to reconstruct the late Quaternary evolution of the inner shelf and coast. The stratigraphy comprises a bedrock basement overlain by a thick (>...

The Holocene shoreface and inner shelf of Tijucas bay, Santa Catarina – Brazil, is part of the extensive wave-dominated, high sediment supply coast of Santa Catarina. The coast comprises accumulations of mixed sand-and-mud representative of a series of muddy tidal flats, overbank deposits and cheniers. In particular, the inner shelf/shoreface is st...
Abstract Shallow geophysical investigations in the upper reaches of North Bay, Florianópolis reveal four seismic facies. These are interpreted as crystalline basement, Quaternary sediments, a bayhead delta and Holocene lagoon/embayment sediments, respectively. The 15 m-thick Bayhead delta unit was deposited on top of a flooded, undulating land surf...

In an era of global rising sea level, quantifying future shoreline behaviour is a key societal concern. The potential for dramatic shoreline change via overstepping or barrier disintegration on barrier-lagoon coasts as a result of future rapid sea level rise has been considered by various authors, but documented examples of barrier overstepping gen...
Large transgressive dune systems are common on the central coast of Santa Catarina, southern Brazil. The aim in this paper is to document changes in the dune morphology over the past 60 yrs and associated changes in extent of the urbanized area and vegetated area of the dune. The aeolian system dynamics and sediment transport to the beach are inter...
Massive fossil shell accumulations require particular conditions to be formed and may provide valuable insights into the sedimentary environments favouring such concentrations. Shallow-water shell beds appear to be particularly rare on reefless volcanic oceanic islands on account of narrow, steep and highly-energetic insular shelves where the poten...

This is the first report on the systematics and the biogeography of the Holocene to Recent shallow marine
Ostracoda of the Azores archipelago (Portugal). Twenty species are herein reported, comprising 10 families
and 14 genera (Neonesidea, Leptocythere, Callistocythere, Cyprideis, Carinocythereis, Aurila, Heterocythereis,
Urocythereis, Loxoconcha,...
This is the first palaeoecological and taphonomical study of the Recent marine ostracods from the Azores. The aims of this work were to address the following questions: i) to establish the typical ostracod assemblages from the shallow waters of the Azores; ii) to determine the bathymetric ranges for each ostracod species; iii) to investigate the ti...
Oceanic islands - such as the Azores in the mid-North Atlantic - are periodically exposed to large storms that often remobilize and transport marine sediments along coastlines, and into deeper environments. Such disruptive events create deposits – denominated tempestites – whose characteristics reflect the highly dynamic environment in which they w...
There is a certain ambiguity in the taxonomy of Amphicytherura Butler & Jones, Aracajuia Krömmelbein and Sondagella Dingle. Recent publications have addressed the separation of these three genera, but a deeper taxonomic analysis is still needed. Aracajuia benderi Krömmelbein, type-species of Aracajuia and an index fossil for the upper Aptian-Albian...

The nine oceanic islands that comprise the Azores archipelago are located in the middle of the northern Atlantic Ocean. In this isolated archipelago, there is a rich fossil record in one of the islands, Santa Maria. In this island, samples were collected in the Upper Miocene composite section of Malbusca outcrop, located in the southern shore of th...
RESUMO:O mapeamento geológico e sedimentar da planície costeira Centro-Norte de Santa Catarina demostrou que, sob o controle básico das variações climáticas e flutuações do nível relativo do mar durante o Quaternário, os sedimentos erodidos das terras altas adjacentes se acumularam em três tipos principais de sistemas deposicionais: (1) um sistema...
In the relatively young archipelago of the Azores, fossiliferous deposits are restricted to the oldest island (Santa Maria), mainly from late Miocene–early Pliocene deposits, and a few from the Pleistocene. echinoid material collected from these deposits comprises mainly disarticulated skeletal material (primary spines and coronal fragments) and a...
In the Açores, the most important, ecologically significant and endangered intertidal habitats, not just here but worldwide, are lagoons and marshes. In the Açorean Archipelago, the largest marsh used to occur between Paúl and Ponta das Contendas at Praia da Vitória on the island of Terceira. The eminent Açorean and Terceiran scientist, Colonel Jos...
