Abstract:Marine survival rates of many juvenile salmon populations have declined in recent decades. Although several potential causes have been proposed, there has been little conclusive evidence for which factors are responsible or not responsible for these declines. We experimen- tally addressed the hypothesis that exposure of coho salmon Oncorhynchus kisutch or sockeye salmon O. nerka to solar ultraviolet-B radiation (UVB) during freshwater rearing of fry and parr life-history stages increases mortality at the time of smoltification and ocean entry. Juvenile coho and sockeye salmon were reared in outdoor hatchery tanks either exposed to full spectrum sun- light or shielded from UVB radiation by plastic screens for up to 9 mo prior to release. Smolts were tagged with acoustic transmitters and detected with hydrophone receivers during their downriver and early ocean migration. Survival of treatment groups was compared using Cormack-Jolly- Seber and Burnham mark-recapture models. While exposure to UVB resulted in decreased growth of juvenile coho salmon, survivorship during the early marine period was unaffected by the UVB treatment for both populations. This first attempt to experimentally address the hypo - thesis of impaired survival resulting from solar UVB radiation has shown that other factors are more likely responsible for observed declines in salmon marine survival rates.

BGRPMN12017 Biodiveristy

Keywords: Occurrence
Temporal coverage: 2010/2016

Sampling data captured in Oceanic Exploration Research Based on geochemical and physical data we identified differences in the polymetallic nodule facies within the eastern German license area. Nodules in Prospective Areas # 1 are generally larger and show significantly higher contents of Ni and Cu as compared to the nodules in Prospective Area #2 which are smaller and are characterised by higher contents of Co. Furthermore, our study shows that sediment, which mainly consists of Si and Al oxides, contributes 13 % to the dry weight of the nodules on average. The method we used is quantitative and can thus be used for habitat mapping and be related to biodiversity and other environmental parameters

Reef Check Med - key Mediterranean marine species 2001-2020

Keywords: Human activities, Ecosystem engineers, Overfishing, diver, Citizen science, Climate change, Non-indigenous species, Protected species, Samplingevent, human
Temporal coverage: 2001/2020

The dataset consists of abundance records of 43 marine species in the Mediterranean Sea from 2001 to 2020. Selected species include some protected and non-indigenous species, ecosystem engineers, species sensitive to climate change, and/or threatened by human activities. Taken together, these taxa represent key ecological aspects of Mediterranean subtidal habitats (Cerrano et al., 2017)  and can be used to calculate the MedSens, an index of the environmental status of subtidal rocky coastal habitats based on species sensitivity (Turicchia et al., 2021). Observations were carried out by the EcoDivers (trained scuba divers, freedivers and snorkelers) according to a rigorous protocol (RCMed U-CEM) developed by the association Reef Check Italia onlus.
Surveys of Octocoral communities, benthic cover and environmental factors on coral reefs of the Great Barrier Reef, Australia (1996 to present)

Keywords: Observation, Occurrence
Temporal coverage: 1996/2008

All surveys were carried out by the principal researcher using Rapid Ecological Assessment. The dataset runs from May 1996: in early 2009 comprising 1636 entries from 180 reef locations, spread relatively evenly along and across the whole Great Barrier Reef (GBR). On each reef 1-3 sites were surveyed with up to 5 transects (usually 200-300m long, 1-3m wide for 10-15 minutes) per site at pre-defined depths (1-3m, 3-8m, 8-13m, 13-18m and reef flat).
Species recorded: octocorals (soft corals, gorgonians, sea fans, sea whips, sea pens, leather corals, arborescent octocorals, blue coral, stoloniferans), black and wire coral. Note that species are mostly at generic level.
Taxa have been matched to the World Register of Marine Species (WoRMS). This dataset was sourced on July 2018 from the original DiGIR dataset at OBIS and updated to reflect changes in the OBIS data requirements.
Tracking  speartooth sharks (Glyphis glyphis) and  bull sharks (Carcharhinus leucas), Wenlock and Ducie rivers, Cape York, Australia (2014-2018)

Keywords: Occurrence, Observation
Temporal coverage: 2014/2018

The study area was located on the Wenlock and Ducie River systems in Cape York, Queensland, Australia (12.350°S, 142.107°E; The region exhibits a distinct wet season, with monsoonal rains followed by a dry season with little to no rainfall. Both the Ducie and Wenlock Rivers flow into Port Musgrave, a large coastal embayment in the eastern  Gulf of Carpentaria. Being tropical tidal rivers, they are subject to daily fluctuations in salinity and to large increases in freshwater inflow .at the onset of the wet season. 

To investigate long-term broadscale movements compared to the changing water conditions, 22 speartooth sharks (Glyphis glyphis) and 22  bull sharks (Carcharhinus leucas)  were fitted with acoustic transmitters and were tracked passively via an array of underwater. acoustic hydrophones.
Tracking data was accessed from the Dryad repository in the cited paper.
DFO Quebec Region Coastal biodiversity of the benthic epifauna of the St. Lawrence Estuary (2018-2019)

Keywords: St. Lawrence Estuary, Biodiversity, St. Lawrence river, Samplingevent, Occurrence, North coast St. Lawrence Estuary, Quebec
Temporal coverage: 2018/2019

The north shore of the Lower Estuary (Haute-Côte-Nord, Québec) is a productive coastal system where many commercial species of benthic invertebrates are fished in the infralittoral (10-20 m) and circalittoral (20-50 m) zones. However, this is an environment where little data exists on the biodiversity of non-commercial species and the environmental characteristics of benthic habitat. This project therefore aims to fill this knowledge gap by developing a framework for collecting biodiversity and environmental data (water column and seabed) which will be used to determine the baseline state of the benthic ecosystem of this region in the depth interval 10-50 m over a period of two years (2018-2019). Benthic species were collected using a beam trawl at selected stations across a depth gradient. Species were identified, counted and weighed.
This project was funded by DFO Coastal Environmental Baseline Program under Canada’s Oceans Protection Plan. This initiative aims to acquire environmental baseline data contributing to the characterization of important coastal areas and to support evidence-based assessments and management decisions for preserving marine ecosystems. /
La rive-nord de l’estuaire maritime (Haute-Côte-Nord, Québec) est un système côtier productif où de nombreuses espèces commerciales d’invertébrés benthiques sont pêchées dans la zone infralittorale (10-20 m) et circalittorale (20-50 m). Cependant, c’est un milieu où peu de données existent sur la biodiversité des espèces non-commerciales et les caractéristiques environnementales de l’habitat benthique. Le présent projet vise donc à combler ce manque de connaissances en développant un cadre de prises de données de biodiversité et environnementales (colonne d’eau et fond marin) qui serviront à déterminer l’état de référence de l’écosystème benthique de cette région dans l’intervalle de profondeur 10-50 m sur une durée de deux ans (2018-2019). Les espèces benthiques ont été collectées à l'aide d'un chalut à bâton (chalut à perche) à des stations sélectionnées sur un gradient de profondeur. Les espèces ont été identifiées, comptées et pesées.
Ce projet a été financé par le Programme sur les données environnementales côtières de référence de Pêches et Océans Canada dans le cadre du Plan de protection des océans. Cette initiative vise à acquérir des données environnementales de base qui contribuent à la caractérisation des zones côtières d’importance et appuient des évaluations fondées sur des preuves ainsi que les décisions de gestion afin de préserver les écosystèmes marins.
Tern Island Albatrosses - 1999

Abstract:
Satellite telemetry was used to identify the foraging distributions of two congeneric species of albatrosses that nest in the tropics/subtropics. Breeding black-footed albatross (<i>Phoebastria nigripes</i>) and Laysan albatross (<i>Phoebastria immutabilis</i>) nesting in Tern Island (Northwest Hawaiian Islands) and tracked during the 1998 breeding season (January - June) performed foraging trips to continental shelves off North America. Black-footed albatross made long trips to the west coast of North America (British Columbia to California). Laysan albatross traveled primarily to the north of the Hawaiian Islands, and reached the waters of the Aleutian Islands and the Gulf of Alaska. These albatross species mixed short and long trips during the chick-rearing period (February - June), but engaged in short foraging trips during the brooding period (within 18 days after chick hatched, January - February).

In 1999, the breeding success of both albatross species was depressed, with a large-scale failure for the Laysan albatross. Out of nine black-footed albatross tracked, two chicks died during this study. Out of sixteen Laysan albatross tracked, the eggs of seven birds did not hatch and eight chicks died during the tracking study. Due to this massive breeding failure, the satellite tracked birds abandoned their colony and dispersed widely across the North Pacific Ocean. Thus, the 1998 (central-place foraging) and 1999 (dispersal from colonies) tracking data should be considered separately.

Purpose:
The 1999 data provided information on albatross movements during a year of depressed reproductive success, when many birds abandoned the colony. An understanding on the interplay between the distribution and the reproductive success of North Pacific albatrosses has important implications for assessing how oceanographic variability influences their population dynamics.

Supplemental information:
These albatross were tracked using PTT-100 Argos transmitters (Microwave Telemetry, Columbia, MD) operating at a 90-second repetition rate and programmed to operate on a 8:24 h ON:OFF duty cycle. Transmitter bench-tests before deployment revealed that the Argos location quality classes (lcs) had the following median position errors, expressed in kilometers: lc B (8.46), lc A (3.29), lc 0 (4.80), lc 1 (1.96), lc 2 (0.49), and lc 3 (0.26).

The low-quality class B locations were discarded because they mis-represented the telemetry tracks. Thus, this dataset includes 4635 high-quality locations (lc classes A or better) with median positional errors &lt;4 km.

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.
