Abstract:
Throughout the years some researchers have dedicated their
efforts to the study of cetaceans’ occurrence off Mainland
Portugal. However, it is still missing a systemic scientific
methodology for studying the presence of coastal dolphins and
whales. This work intends to be a first approach on the occurrence of cetaceans off the west central coast of Portugal. Our objective was to contribute towards the compilation of relevant “forgotten science” such as whaling data and observations of opportunity, together with two years of boat-based surveys.
We found 1,313 occurrences of great whales captured off
Setúbal and Sesimbra (1925-1927 and 1944-1951) and a total
of 45 cetaceans in non-directed captures between 1976 and
1978. We accounted 45 dolphins and whales in sea-sightings
as a result of observations of opportunity, from 2002 to 2008.
In 2007 and 2008 a total of 63 boat-based visual surveys were
conducted from three different geographic locations, Nazaré,
Peniche and Sesimbra, and as a result 45 independent sightings
of cetaceans were recorded. The most frequent small dolphin
off the Portuguese mainland coast is the common dolphin
(<i>Delphinus delphis</i>) as shown by the three distinct approaches used in this study. Regarding whales the most common species is the fin whale (<i>Balaenoptera physalus</i>) as shown by whaling records. Overall, the small delphinid community along the central coast of Portugal is similar to the one that can be found along the Iberia shore.
This dataset contains only the boat-based sightings.

Purpose:
This work intends to be a preliminary approach on the
occurrence of cetaceans off the west central coast of Portugal.
Our objective was to contribute towards the compilation of
relevant “forgotten science”, namely 20th century whaling and
dolphin capture data and opportunistic observers’ reports on
whales and dolphins, in order to reduce the lack of knowledge
in central mainland Portugal. This information together with
boat-based surveys for obtaining new biological data is a
starting point for a new methodological approach.

Supplemental information:
Records did not have time recorded and were filled with 00:00:00. Records that did not have group size recorded were filled with 1. When an estimated range of animals was sighted, the median value (rounded down) was used as the observed count. Time and group size details are recorded in the [Notes] column.
Three opportunistic sightings of <i>Delphinus delphis</i> recorded for August 2007 were excluded because the day information was not available. One erroneous record of <i>Delphinus delphis</i> sightings on land was also excluded.

Antarctic Nemertea

Keywords: Occurrence
Temporal coverage: null/null

Open-ocean environments provide few obvious barriers to the dispersal of marine organisms.
Major currents and/or environmental gradients potentially impede gene flow. One
system hypothesized to form an open-ocean dispersal barrier is the Antarctic Polar Front,
an area characterized by marked temperature change, deep water, and the high-flow Antarctic
Circumpolar current. Despite these potential isolating factors, several invertebrate
species occur in both regions, including the broadcast-spawning nemertean worm Parborlasia
corrugatus. To empirically test for the presence of an open-ocean dispersal barrier, we
sampled P. corrugatus and other nemerteans from southern South America, Antarctica, and
the sub-Antarctic islands. Diversity was assessed by analyzing mitochondrial 16S rRNA
and cytochrome c oxidase subunit I sequence data with Bayesian inference and TCS haplotype
network analysis. Appropriate neutrality tests were also employed. Although our
results indicate a single well-mixed lineage in Antarctica and the sub-Antarctic, no evidence
for recent gene flow was detected between this population and South American P. corrugatus.
Thus, even though P. corrugatus can disperse over large geographical distances, physical
oceanographic barriers (i.e. Antarctic Polar Front and Antarctic Circumpolar Current)
between continents have likely restricted dispersal over evolutionary time. Genetic
distances and haplotype network analysis between South American and Antarctic/
sub-Antarctic P. corrugatus suggest that these two populations are possibly two cryptic species.
Marine Invertebrate from Argentina, Uruguay and Chile

Keywords: Uruguay, biodiversity, marine invertebrate, Chile, Argentina, Occurrence
Temporal coverage: null/null

Data on invertebrate taxa were obtained from available literature, technical reports, databases, museum data collections and from the NaGISA project in the case of Golfo Nuevo rocky shore invertebrates. It should be taken into account that the data presented here does not represent a revision of the identifications. Species must be evaluated through the material deposited in museum collections or by searching the species in the locality or area that they were cited. However, and although data presented must be verified by experts of each group, these results should reflect the current knowledge of marine invertebrate biodiversity in the analyzed area. Georeferences are consigned as latitudinal and longitudinal ranks when a continuous distribution is assumed, and with data-points in case of discontinuous distribution.
Fish observations delivered by "Canarias por una Costa Viva" project

Temporal coverage: 2003/2005

The project ‘Canarias, por una costa viva (CCV)’ was an integrated research and educational initiative that run between 2003 – 2004 with the goals of gathering robust scientific information of keystone coastal habitats and the promotion of public awareness about responsible uses of marine resources in the Canary Islands (Central East Atlantic Ocean). Sampling effort has been carried out biannually at 100 locations around the coastlines of the overall Canary Islands. Specifically, we have studied the conservation status of key fish species and their role in their ecosystems. The relationship between the human population, the natural environment and the pressures it supports has been observed in different anthropogenically stressed areas (sewage areas, shell fishing activity, sea-cage fish farms and ports) and preserved areas

Abstract:
We present marine mammal observation statistics, high-frequency seismic source characteristics, and example denoising of marine mammal acoustical recordings using data collected during the mitigation and monitoring program for a 3-D seismic survey by Encana Corporation, Calgary, Alberta, Canada, in the northwest Atlantic during 2003. Marine mammals were observed both visually and acoustically. No marine mammal incidents or adverse reactions were observed during the survey.

Acoustical observations were made by the Seamap Passive
Acoustic Cetacean Monitoring System (SPACMS), consisting of
two hydrophones placed 50 m apart, towed ahead of and to one
side of the seismic source. Visual and acoustical detections were uncorrelated, indicating the complementary nature of the two observational techniques. Visual detections were more common per hour of effort than acoustical detections. Acoustical detection rates showed no significant day–night difference.

Marine mammals appeared to have avoided very close ranges (100 m) from the seismic array during seismic acquisition, but the overall number of marine mammals in the observable radius (1–2 km) did not change significantly when the seismic source was “on” compared to “off.” Marine mammals were observed in larger groups and appeared to have become less vocal when the seismic source was active. It should be noted however, that the results from this data gathering effort may be affected by potential sources of bias (such as the combination of data from toothed and baleen whales).

Signal processing of seismic source signatures indicated some
high-frequency energy content consistent with expectations from
earlier work. This analysis confirmed that most of the seismic
energy was concentrated at lower frequencies (500 Hz). No
low-frequency comparisons with near-field data could be made
due to the geometry of the SPACMS recording hydrophones
and seismic source, which resulted in the Lloyd’s mirror effect
obliterating low-frequency components in the SPACMS records.
A wavelet-based denoising method was applied to improve the visibility of marine mammal vocalizations on a spectrogram display.

Abstract:
Sperm Whale Seismic Study (SWSS) was a multi-institutional, interdisciplinary research project supported by the then Minerals Management Service (MMS; now Bureau of Ocean Energy Management - BOEM) under Cooperative Agreement 1435-01-02-CA-85186 for Cooperative Research on Sperm Whales and their Response to Seismic Exploration in the Gulf of Mexico through the Texas A&amp;M Research Foundation.

The objectives of SWSS were to
(1) establish baseline information on the biology and behavior of sperm whales in the northern Gulf of Mexico,
(2) characterize sperm whale habitat use in the northern Gulf of Mexico, and
(3) determine possible changes in behavior of sperm whales when subjected to manmade noise, particularly from seismic airgun arrays used for offshore oil and gas exploration and geological monitoring.

Abstract:
These data were collected via land-based observations from Poludennaya Bay, Beringa Island (Commander Islands) in May-June 2007, May-July 2008 and August-September 2009. The observation point was located on a 40 m cliff. Bearing and distance to the observed whales were defined by binoculars with a compass and range-finding reticle. Observations were conducted during all daylight hours, if visibility was more than 5 km. We made one 15 minute scan every half hour and noted all cetaceans observed during the scan. Consequently, in many cases we could note the same animal several times in different scans. Observed species include killer whale, minke whale, humpback whale, fin whale, sei whale, sperm whale, Baird’s beaked whale, harbor porpoise and Dall’s porpoise.

Purpose:
The purpose of this study is to identify critical habitats for various cetacean species in the waters of the Russian Far East.

Species composition and distribution of net plankton diatoms in the Pacific sector of the Antarctic Ocean 1963-4

Keywords: Occurrence, Observation
Temporal coverage: 1963/1964

The water mass designated as the Southern or Antarctic Ocean is among the most productive areas of the world. In spite of the recent emphasis on biological oceanographic research, the species composition and distribution of the primary producers, mostly diatoms, has not been thoroughly examined in many areas. Knowledge of the organisms involved in primary production is of special interest as man considers use of marine resources to meet the needs of expanding world population. Phytoplankton diatoms in the Antarctic are the major food source for the tremendous krill (Euphausiacea) populations, which in turn are the food source for many of the large whale, seal, fish, and bird populations in this area. It is necessary to understand the species composition and ecology of the Antarctic primary producers and their relationship to the consumer levels in the food web before adequate use of the abundant marine resources of the Antarctic Ocean can proceed. This work is concerned with the most basic problem involved, the species composition of the phytoplankton diatoms and their distribution.
