Abstract:
From 4 to 13 August 1991, as part of a larger study, Alaska harbor porpoise (<i>Phocoena phocoena</i>) abundance was investigated during an aerial survey throughout the coastal waters of Bristol Bay. A Twin Otter was used as the survey platform and was flown at an altitude of 152.2 m (500 ft) and at an airspeed of 185 km/h. The third of three identical sawtooth track lines was flown along the south side of Bristol Bay. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Density of harbor porpoises was calculated using line transect estimates based on perpendicular distances of sightings to the cruise track of the airplane. On average, porpoise group size and density for Bristol Bay was 1.17 (SE = 0.35) and 4.48 groups/100 km2 (SE = 1.38).

Purpose:
Although harbor porpoises, <i>Phocoena phocoena</i>, are known to occur throughout Alaska waters, few estimates of abundance exist. In 1991, the National Marine Mammal Laboratory initiated a 3 year study on Alaska harbor porpoises. The objectives of this program were to:
1) Obtain minimum population estimates in coastal waters using line transect methodology with a coefficient of variation for density estimates of less than 30% for each survey area, and 
2) Establish a baseline for detecting changes in abundance through time, for analysis of trends.
During the present study, it was not fiscally possible to survey all areas of the state in any one year. Accordingly, we selected sections of the state to survey in consecutive years to maximize the likelihood of including all of the animals for a particular area surveyed while minimizing the likelihood of significant movement between areas among survey years.

International Polar Year and Census of Antarctic Marine Life Ross Sea voyage (TAN0802) biodiversity data

Keywords: Occurrence, Observation
Temporal coverage: 2004/2008

Biological data from the IPY-CAML voyage (TAN0802) by the R/V Tangaroa. The TAN0802 voyage departed from Wellington, New Zealand on Jan 26th 2008 and returned to Wellington, New Zealand, on Mar 21st 2008. The survey was concentrated mainly on the Ross Sea and the waters around Scott and the Balleny Islands. Biological data was collected using a variety of gear, including: bottom trawls, beam trawls, epibenthic sleds, Van Veen grabs, Rosette water bottle and MOCNESS tows.
The voyage resulted from a announcement by the Prime Minister in 2007 for new government funding for a New Zealand Census of Antarctic Marine Life (CAML) project to support biodiversity studies in the Southern Ocean and Ross Sea Region as part of the governments Ocean Survey 20/20 (OS2020) programme and the International Polar Year (IPY) activities. The overall Project includes two phases a) data collection voyage and b) data analysis and reporting. 
The recognition of International Polar Year (IPY) throughout the globe from March 2007 to March 2009 has provided the impetus for a large international effort to conduct collaborative research both in Antarctica and the Arctic, spanning two summer seasons in both regions. New Zealand is participating in a range of both terrestrial and marine projects for IPY that are important, not only nationally, but also in the international science arena.
The Census of Antarctic Marine Life (CAML) is a major multi-national IPY Programme that New Zealand’s project is part of. This project forms a particularly important component of the international CAML Programme, as it will not only be part of the circum-polar national surveys, but will provide an opportunity to compare fauna and ecosystems from opposite sides of the globe including the two most significant shelf areas in Antarctica-the Ross Sea and the Weddell Sea.

Abstract:
In the Black Sea the cetaceans are represented by three species, Phocoena phocoena relicta, Tursiops truncatus ponticus and Delphinus delphis ponticus.
The main threat and cause of decline for the Black Sea dolphins are the fishing nets, so-called bycatches.
For protection of the dolphin populations from Romanian Black Sea area in conformity with the objectives of the „National Action Plan for Conservation of Dolphins” and „Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and contiguous Atlantic Area”, with finance from European Union true the Sectorial Operational Programme – Environment, NGO "Mare Nostrum” started a series of activities in partenership with National Institute for Marine Research and Development „Grigore Antipa” Constanța, Danube Delta Biosphere Reserve Authority, National Agency for Fishing and Aquaculture,
Natural Science Museum Complex „Dolphinarium” Constanța, Border Police Inspectorate of Constanța County.Among these activities we will present in the following study the
situation of strandings and by-catch of dolphins in the Romanian costal waters during 2010 and 2011. The datas were collected from the entire Romanian coast, from Sulina to Vama Veche.
During the study more than 100 expeditions were done by land and water along the coast. Data collected recorded over 140 dead cetaceans and 1 alive; the maine cause of this mortality was due to drowning in the fishing nets.
To reduce the number of bycatched dolphins we are studing the effect of pingers (ADD/Acustic deterent devices) on cetaceans and fishes. In this order data were collected from five fishing units (Sulina, Vadu, Corbu, Midia, Costinești) equipped with these technologies. This measure of protecting the dolphins from the fishing nets is proposed also in ACCOBAMS.

Purpose:
Collecting data regarding sightings of the Black Sea cetacean at the Romanian coast.

Sizing Ocean Giants

Keywords: Observation, Occurrence
Temporal coverage: 1817/2013

What are the greatest sizes that the largest marine megafauna obtain? This is a simple question with a difficult and complex answer. Many of the largest-sized species occur in the world’s oceans. For many of these, rarity, remoteness, and quite simply the logistics of measuring these giants has made obtaining accurate size measurements difficult. Inaccurate reports of maximum sizes run rampant through the scientific literature and popular media. Moreover, how intraspecific variation in the body sizes of these animals relates to sex, population structure, the environment, and interactions with humans remains underappreciated. Here, we review and analyze body size for 25 ocean giants ranging across the animal kingdom. For each taxon we document body size for the largest known marine species of several clades. We also analyze intraspecific variation and identify the largest known individuals for each species. Where data allows, we analyze spatial and temporal intraspecific size variation. We also provide allometric scaling equations between different size measurements as resources to other researchers. In some cases, the lack of data prevents us from fully examining these topics and instead we specifically highlight these deficiencies and the barriers that exist for data collection. Overall, we found considerable variability in intraspecific size distributions from strongly left- to strongly right-skewed. We provide several allometric equations that allow for estimation of total lengths and weights from more easily obtained measurements. In several cases, we also quantify considerable geographic variation and decreases in size likely attributed to humans.

Abstract:
The Marine Spatial Planning (MSP) project in Suriname was initiated in 2017. Part of this EU-funded project focussed on collecting all the information regarding marine megafauna within the region (Suriname and Guyana). As part of the MSP project we searched for potential marine megafauna data holders and different data-sets were found: 
(1) research data: published and unpublished data collected during dedicated (effort-related) marine fauna surveys (where a GPS track was available); 
(2) data collected by Marine Fauna Observers during geophysical seismic surveys (without an available GPS track); 
(3) Opportunistic data collected without keeping track of effort (e.g. website, social media and other sighting records collected by university students or citizens); and 
(4) Systematic land-based observations carried out during sea turtle surveys on Braamspunt. Here you can find all opportunistic records of marine megafauna in Suriname, including coastal and offshore regions. For the MSP-project we used records which were classed as 'Definite' or 'Probable'. Where 'Definite' records were accompanied by photo; and 'Probable' records had a good description and were coming from a trusted source. Other records with 
an unsure identification (for example  'possible green turtle'), were upgraded to 'Probable' records of species-groups, e.g. 'hard-shelled turtle', 'ray species', 'shark species', 'dolphin sp'. All other records were discarded. NB all bird records submitted by the holders of the 
database 'Birds of Suriname' were classed as 'Definite'.

Purpose:
The project aims to significantly enhance the governance and protection of marine and coastal resources of Guyana and Suriname through collaborative processes with all ocean stakeholders, improved knowledge of the coastal and marine environment, enhanced capacity of key stakeholders and informed marine spatial management. Upon completion of the marine Spatial planning project, we aim to continue to add new marine megafauna records to OBIS SEAMAP.

Este conjunto de datos corresponde a inventario de especies de macroinvertebrados intermareales asociados a bosques de manglar y litorales arenosos en el área comprendida entre la Bahía de Tumaco y Candelilla de la Mar en la Costa Pacífica del Departamento de Nariño – Colombia.
La propuesta de este proyecto surgió a lo largo del desarrollo de la Expedición Pacífico 2018, cuando se apreció la gran diversidad y abundancia de especies de invertebrados entre las raíces de manglar y en los playones formados durante la marea baja. En vista de lo anterior, se inició una recopilación de conchas y registros fotográficos para identificar las especies, así como reuniones con pobladores de cada localidad visitada y con representantes del Consejo Comunitario Bajo Mira y Frontera, para compilar información tradicional sobre las especies en la zona. Finalmente, surgió la idea de generar un catálogo de las especies encontradas, pero con un diseño vistoso, mucho material gráfico y lenguaje sencillo, para poder socializarlo y distribuirlo entre la población local.
En total se registraron 50 registros durante la expedición.
DMNS Marine Invertebrate Collection (Arctos)

Keywords: Specimen, Occurrence
Temporal coverage: 1879/2022, 1700/2022

The Denver Museum of Nature &amp; Science Marine Invertebrate Collection dates to the early 1900s. It is a diverse collection of worldwide specimens, the largest portion being marine shells. It also has specimens of echinoderms, corals, sponges, crustaceans, and other invertebrates. Despite its name, it includes a substantial collection of land and freshwater snail shells. The collection contains nearly 50,000 lots, of which more than half are databased in Arctos with more being added to the database each week. More than half of the databased lots are geolocated, and over 1,000 specimen records have images. 

Specimens in the collection represent nearly 6,000 species in over 450 families. Specimens come from over 150 countries with the majority from the United States and most of those from Florida and Hawaii.   All specimens have been donated to the Museum by shell collectors, including many self-collected specimens.
