Macroalgas de la bahía de Macuro, estado Sucre, Venezuela. Estudio de línea base previo a la mejora del muelle de Macuro

Keywords: CaribeSur, biomasa, Golfo de Paria, taxonomía, macroalgas, BID-CA2020-025-NAC, Samplingevent
Temporal coverage: 2014/2014

Las macroalgas constituyen uno de los grupos más empleados en estudios de impacto en zonas costeras por su fácil manejo y la presencia de especies con diferentes grados de sensibilidad ante los cambios ambientales. En mayo de 2014  se colectaron macroalgas en 5  estaciones  en  la bahía de Macuro (estado Sucre), se tomaron muestras para estudios taxonómicos y se usó una cuadrata para delimitar el área de los especímenes para la determinación de la biomasa algal. La identificación de las especies de macroalgas se hizo mediante el uso de claves taxonómicas, la biomasa se obtuvo por especie mediante el secado en una estufa para la obtención del peso seco expresado en g.m-2.  Se identificaron 23 macroalgas, de las cuales el mayor porcentaje correspondió a las Rhodophyta (61 %). Las categorías taxonómicas distribuidas por Phylum según el esquema Orden-Familia-Género-especie, fue el siguiente: Rhodophyta (5-7-10-14), Ochrophyta (3-3-4-4) y Chlorophyta (3-5-5-5). La especie con mayor biomasa fue Padina gymnospora en las estaciones 1 y 2, con 23,02 y 10,6 g.m-2 respectivamente. La especie  más constante en todas las estaciones fue Centroceras clavulatum. Las asociaciones de algas mostraron un complicado ensamblaje para Macuro, con un predominio de algas rojas, formando mantos que sirven de refugio a una gran diversidad de invertebrados (moluscos, crustáceos, poliquetos y briozoarios, entre otros taxa).  La presencia de algas en el golfo de Paria está fuertemente condicionada por la disminución de la salinidad e incremento de la turbidez ocasionada por el aporte de aguas ricas en sedimentos provenientes del río Orinoco, y por el predominio de sustratos areno-fangosos, aunque la existencia de sectores rocosos en la costa favorece el establecimiento de las macroalgas.

Abstract:
The status of Ireland's harbor seal <i>Phoca vitulina vitulina</i> population is poorly understood. The most recent national population estimate dates back to the breeding season in 1978 and did not cover the entire coastline. Reliable up-to-date information on the abundance and distribution of harbor seals in Ireland is necessary to assess the conservation status of the species and for the effective identification, management and monitoring of special areas of conservation required for harbor seals under the European Union Habitats Directive. To provide comprehensive current information on Ireland's harbor seal population, a geographically extensive survey was conducted along the coastline of the Republic of Ireland during the species' annual moult in August 2003. This complemented a similar survey of Northern Ireland, which was conducted in 2002. Using thermal imaging technology, haul-out groups of harbor seals and grey seals <i>Halichoerus grypus</i> were identified from the air, aerial-counts were obtained and compared with simultaneous ground-count data from selected sites. Harbor seal distribution recorded during the 2003 moult season was concentrated in the south-west, west and north-west of the country. This national survey yielded a minimum population estimate for the Republic of Ireland of 2905 harbor seals, delivering an effective baseline for current and future population research.

Supplemental information:
This dataset also includes ancillary grey seal data, showing summer terrestrial distribution of grey seals. This data cannot be used for estimating population size of grey seals as this is conducted during the winter breeding season.

SEAPOP NINA

Keywords: Occurrence, Long term follow up, Observation
Temporal coverage: null/null

SEAPOP (SEAbird POPulations) is a long-term monitoring and mapping programme for Norwegian seabirds that was established in 2005. The programme represents a new initiative for these activities in Norway, Svalbard and adjacent sea areas, and will provide and maintain base-line knowledge of seabirds for an improved management of this marine environment. The data analyses aim to develop further models of seabird distribution and population dynamics using different environmental parameters, and to explore the degree of covariation across different sites and species. This knowledge is urgently needed to distinguish human influences from those caused by natural variation.
Location of  stopping sites from satellite tracking of 25 bar-tailed godwits (Limosa lapponica)  in the East Asian–Australasian Flyway (EAAF). (2015-2017)

Keywords: Observation, Occurrence
Temporal coverage: 2015/2018

Bar-tailed godwits were captured by cannon netting at two non-breeding sites in northwest Australia: at the northern beaches of Roebuck Bay (17.98°S, 122.35°E) in October 2014 and 2015 and February 2017 and at the central and northern portions of Eighty Mile Beach (19.40°S, 121.27°E), in February 2017.  Stopping sites in the East Asian–Australasian Flyway (EAAF) (including ‘staging sites’, i.e. sites where migrating birds make long stops, and ‘stopover sites’ where birds make short stops), were extracted by first clustering consecutive points where rate of movement was under 5 km h−1 and then grouping all clusters within 20 km of each other.

Stopping sites data accessed from cited paper on 2022-12-01. There are three other datasets in OBIS linked to the East Asian–Australasian Flyway (EAAF).
DFO Pacific Outside North Hard Bottom Longline Surveys

Temporal coverage: 2006/2019, 2006/2021

The Outside North Hard Bottom Longline (HBLL)  survey is one of a set of long-term and coordinated surveys that together cover most of the nearshore, hard-bottom habitat of coastal British Columbia. The other surveys are the Outside South HBLL survey, Inside North HBLL survey, and Inside South HBLL survey.
The Outside North HBLL survey was first conducted in 2006 and has been repeated every second year in alternate years to the Outside South HBLL survey, with the exception that no surveys were conducted in 2013.   The survey was not impacted by the COVID-19 pandemic. The objective of these surveys is to provide fishery-independent abundance indices and associated biological data for the assessment of nearshore rockfishes and other groundfish species that live on untrawlable, hard bottom habitats. The surveys follow a random depth-stratified design and the sampling units are 2 km by 2 km blocks. The Outside HBLL surveys use size 14/0 circle hooks, baited with frozen squid.
The Outside North HBLL Survey is conducted by DFO in collaboration with the Pacific Halibut Management Association (PHMA) and takes place on several chartered commercial fishing vessels each year. This survey covers the northern portion of the British Columbia coastline, including the mainland coast north of Milbanke Sound, Dixon Entrance, and the east and west coasts of Haida Gwaii. The PHMA provides the chartered commercial fishing vessels and field technicians, while DFO provides support for running the surveys, including survey design and equipment.
The data provided include information about the annual survey trips and fishing events (tows/sets) that are part of this survey series, including the vessel name, dates, times, spatial coverage, gear details, and effort information. Catch information (total weight in kg or counts of individual specimens) is included from successful fishing events. Catches are identified to species or to the lowest taxonomic level possible. Most catches are weighed, but some are too small (“trace” amounts) or too large (e.g. very large Big Skate). Some catches were subsampled and biological data were collected from individual fish specimens, including length, sex, and weight information. Where age structures were collected and processed, fish ages have been included.

Abstract:
The United States (US) Navy uses the Southern California (SOCAL) portion of 
the Hawaii-Southern California Training and Testing area, a collection of 
nearshore and offshore training areas that include much of the navigable 
water from Santa Barbara Island, California, to northern Baja California, 
Mexico, and extending several hundred miles to the west. It is among one of 
the most heavily used tactical training areas in the world, and is used for a 
variety of aerial, surface, and subsurface exercises. The Southern California 
Offshore Range (SCORE) is a subset of complexes within SOCAL centered on 
San Clemente Island and managed via the Range Operation Center (ROC) on 
North Island, Coronado. It includes the Southern California Anti-submarine 
Warfare Range (SOAR), a focal area for exercises involving mid-frequency 
active sonar (MFAS) systems within the San Nicolas Basin.

Through its N45 Living Marine Resources (LMR) research programs, and more 
recently in support of Pacific Fleet Monitoring efforts, the US Navy has funded 
directed studies on cetacean occurrence on SOAR since 2006. The primary 
focus of these studies is to support long-term surveys of Cuvier’s beaked 
whales and fin whales using photo-identification (photo-ID) and genetics to 
elucidate population size, structure, and trends, which can in turn provide a 
particularly robust basis for assessing population-level impacts of Navy 
training. Data is collected on all species encountered in this region as part of 
the monitoring program.

Purpose:
Data from this project is collected to better understand the movement and 
habitat use of cetaceans within and around the Southern California Bight (SCB). 
The SCB is home to a diverse group of cetacean species, and is an area of 
significant human impacts, including commercial shipping, Navy training, and 
recreational boating.

These surveys were funded by Fleet for Southern California.
TPWD HARC Texas Coastal Fisheries Corpus Christi Bay Trawl

Keywords: Occurrence, Observation
Temporal coverage: 1982/2008

The Texas Parks and Wildlife Department (TPWD) utilizes several sampling gears for fisheries-independent monitoring of finfish and shellfish communities. They include bag seines, trawls, gill nets and oyster dredges. TPWD uses multiple gears in a random sampling protocol, and they identify (to the lowest taxonomic unit possible) and count everything that they collect. This dataset contains trawl data collected for the Corpus Christi bay system in Texas from 1982 to 2008. Collected data also included spatial and temporal information describing the sample location and time, collection gear information, hydrological data (e.g. dissolved oxygen, water temperature, and salinity), weather conditions, species caught, and number of each species captured. Houston Advanced Research Center (HARC) calculated the relative abundance data, calculated as the catch of a particular species in a sample divided by the total number of animals captured in that sample. Absence data was recorded for species on the TPWD species sampling lists that were not captured during sampling.
