Os oceanos são usados pelo homem há centenas de anos, no entanto, seu estudo é acontecimento relativamente recente, sendo a maior parte exercida no ensino superior. Este trabalho pretendeu desenvolver metodologia utilizando a Oceanografia como ferramenta para desenvolvimento interdisciplinar dos conteúdos científicos no Ensino Fundamental II. Em escola localizada na Zona Oeste de São Paulo, estudantes de duas turmas do 5° ano de escolarização participaram de trabalho de estudo do meio, experimento em laboratório utilizando Artemia salina (Crustacea: Branchiopoda), debate e questionários abertos (aplicados como pré e pós-teste) sobre problemas ambientais e conflito de interesses numa cidade hipotética. As respostas a três das questões que enfocavam alterações físicas, influência dessas alterações na biota e propostas para resolução do problema foram analisadas qualitativamente e enquadradas em modelos organizadores do pensamento. A metodologia utilizada mostrou-se adequada a este nível de ensino. Observou-se que para responder às questões do pós-teste os alunos utilizaram habilidades e conhecimentos prévios, adquiridos em viagem de estudo do meio, em laboratório e no debate. Notou-se também aperfeiçoamento da linguagem científica e busca de caminho consensual ou democrático para resolver o problema proposto. Por fim...

Lulas da família Loliginidae são recursos pesqueiros em crescente importância no ecossistema marinho da Plataforma Continental Sudeste (PCSE) do Brasil. No entanto, informações sobre a distribuição dos estágios iniciais do seu ciclo de vida são bastante escassas. Com base em amostras de plâncton coletadas por 11 cruzeiros oceanográficos pretéritos do Instituto Oceanográfico da USP entre 1991 e 2005, o presente estudo teve como objetivo a identificação da ocorrência de paralarvas de Loliginidae na região entre o Cabo de São Tomé (RJ) e Cananéia (SP). Das 644 amostras analisadas, foram encontradas 246 paralarvas, sendo 121 identificadas em nível de espécie (Doryteuthis sanpaulensis n=75, Doryteuthis plei n=39, Lolliguncula brevis n=6 e Pickfordiateuthis pulchella, n=1). Os padrões de distribuição da Família em relação aos processos oceanográficos foram identificados a partir de mapas de distribuição horizontal e vertical de abundância, temperatura e salinidade. Modelos Lineares Generalizados (GLMs) foram utilizados para detectar os fatores que explicariam a ocorrência e a abundância de Loliginidae, os quais indicaram que a profundidade e a temperatura superficial do mar são as principais variáveis explanatórias. Uma Análise de Redundância (RDA) evidenciou os principais padrões de distribuição observados das três principais espécies de Loliginidae em relação às variáveis oceanográficas. D. sanpaulensis predominou na região norte da área de estudo...

Onshore sediment transport and sandbar migration are important to the morphological evolution of beaches, but are not understood well. Here, a new model that accounts for accelerations of wave-orbital velocities predicts onshore sandbar migration observed on an ocean beach. In both the observations and the model, the location of the maximum acceleration-induced transport moves shoreward with the sandbar, resulting in feedback between waves and morphology that drives the bar shoreward until conditions change. A model that combines the effects of transport by waves and mean currents simulates both onshore and offshore bar migration observed over a 45-day period. A stochastic nonlinear Boussinesq model for the evolution of waves in shallow water is coupled with the wave-acceleration-driven sediment transport model to predict observed onshore sediment transport and sandbar migration given observations of the offshore wave field and initial bathymetry. The Boussinesq-wave model has skill in predicting wave spectra, as well as velocity and acceleration statistics across the surfzone, but it underpredicts acceleration skewness on top of the sandbar. As a result, the coupled wave-sediment transport model underpredicts sediment transport, and thus fails to move the sandbar onshore. Although the coupled wave and sediment model can be tuned to yield skillful predictions of onshore sandbar migration...

Data assembly and processing centers are essential elements of the operational oceanography infrastructure. They provide data and products needed by modeling and data assimilation systems; they also provide products directly useable for applications. The paper discusses the role and functions of the data centers for operational oceanography. It describes some of the main data assembly centers (Argo and in-situ data, altimetry, sea surface temperature) developed during GODAE. An overview of other data centers (wind and fluxes, ocean colour, sea ice) is also given. Major progresses have been achieved over the past 10 years to validate, intercalibrate and merge altimeter data from multiple satellites.; JRC.DDG.H.3-Global environement monitoring

This summary continues a series of reports on the project, which seeks to assemble a census of marine mammal vocalizations in the high--frequency acoustic recording package (HARP, Wiggins and Hildebrand, 2007) data collected by the NPS Oceanography Department off Point Sur beginning in October 2006. The present report provides an initial summary of marine mammal vocalizations detected and identified in records from the sixth HARP deployment between February 1, 2009 and April 30, 2009. Data was acquired in the 10 Hz -- 100 kHz frequency band at a 200 kHz sampling frequency for 5 minutes during each 10 minute interval. Long-term spectral averages were created for three frequency bands (10 Hz--1000 Hz, 1 kHz-5 kHz, 5 kHz--100 kHz) and then scanned for marine mammal vocalizations. Detected calls of fin whales, humpback whales, as well as echolocations of sperm whales, beaked whales, and dolphins are presented as occurrence time diagrams.

In August 1992 a combined physical oceanography and acoustic tomography experiment was conducted to describe the Barents Sea Polar Front (BSPF) and investigate its associated mesoscale phenomena. The study area was an 80 by 70 km grid east of Bear Island where the front exhibits topographic trapping along the northern slope of the Bear Island Trough. CTD, current meter and CP data, combined with tomographic cross-sections, presented a highly resolved picture of the front in August. All hydrographic measurements were dominated by tidal signals with the strongest signatures associated with the M2 and S2 semidiurnal species. Tomographic cross sections indicated a high-frequency (approx 16 cpd) upslope motion of filaments of Norwegian Atlantic Water (NAW) origin at the front. Mean currents in the warm saline water to the south of the front, derived from a current meter mooring and CP data, were directed to the southwest and are associated with a barotropic recirculation of NAW within the Bear Island Trough. To examine the relation of BSPF to the regional oceanography, a high resolution (1/60 and 30 vertical levels) Arctic Ocean and Nordic Seas model was developed from the Semmer-Cherrin General Circulation Model (GCM) with a free-surface. Three numerical experiments...

During FY00, Professors Wash and Rosenfeld of the Naval Postgraduate School's Meteorology and Oceanography Departments, respectively, made extended visits to each of the Naval Meteorology and Oceanography Command's regional centers and facilities for the purposes of providing training, evaluating the use of METOC data, models, and tactical decision aids, and gathering information to aid in the improvement of the METOC curricula at NPS. This report represents a synopsis of their findings integrated over all of their visits. Three major roles for METOC regional centers and facilities are identified: (1) to be a source of local METOC knowledge and expertise for their area of responsibility, including familiarity with mesoscale circulations and all reliable sources of real-time data and model output; (2) to provide operational support to the fleet, including customized fused products and littoral oceanography products; and (3) to provide training for METOC personnel in regional-specific meteorology and oceanography, and continuing advanced technical training. A major finding is that technical education and training is inadequate to allow METOC personnel to take maximum advantage of the full range of data, models, and tactical decision aids available to them. Weaknesses in the quality-control and verification of METOC analysis and forecast products are also identified. A number of innovative practices at individual commands are recommended for adoption throughout the claimancy.

After the discovery of a forty foot shipping container resting on the ocean floor within the Monterey Bay National Marine Sanctuary (MBNMS), the MBNMS began a study to research the impact that containers lost at sea might have on the marine environment. The Naval Postgraduate School Oceanography Department was approached to provide some measure of the total shipping which passes within the boundaries of the MBNMS. Utilizing the Automated Identification System (AIS) message data, both total shipping and cargo shipping totals were calculated and monthly density plots were generated to show those areas which are most impacted by vessel traffic. In addition to providing informing the issue of lost shipping containers, these plots can also be used by the MBNMS and NOAA's other West Coast Sanctuaries to understand interactions between shipping and wildlife, especially within the context of ship strikes to whales.

Communication presented at the 14th International Congress on Sound Vibration, Cairns, Australia, 9-12 July 2007.; Seismic reflection is a technique used for decades to profile the earth layering beneath the ocean with a high lateral and vertical resolution. In the other hand, oceanographers use probes to obtain the properties of the water layer with a rather lesser lateral resolution. Seismic oceanography focuses the powerful tools of seismics into the water layer to reveal its fine structure with a high lateral resolution. The re-processing of the in-water reflected waves in seismic data has allowed to image eddies, termohaline intrusions and internal waves. Synthetic models of such seismic experiments in water permit to foresee the effects of oceanographic gradients in the propagated waves. This paper describes a synthetic model of such seismic oceanography experiments. The model uses Berkhout convolution operators to extrapolate the wave field from the seismic source to the hydrophones taking into account the sound velocity structure of the water layer. Due to the small amplitudes of the scattered field, special attention is paid to the absorbing properties of the artificial boundaries of the medium.; This research has been supported by the CSIC...
