The Ocean Data Viewer offers users the opportunity to view and download a range of spatial datasets that are useful for informing decisions regarding the conservation of marine and coastal biodiversity. These decisions ultimately affect the ocean's health and productivity, which provide the ecosystem services that are necessary for our well-being, livelihoods, and survival. To date, the users of this tool have included government agencies, scientists, researchers, the corporate sector, and non-governmental organisations. These data come from internationally respected scientific institutions and other organisations that have agreed to make their data available to the global community, with the hope that these data will support and encourage informed decision-making that sustains global biodiversity and ecosystem services. The Ocean Data Viewer is primarily a mechanism to view and download data, and is not intended to be used for analysis or to query data.

NCAR was established by the National Science Foundation in 1960 to provide the university community with world-class facilities and services that were beyond the reach of any individual institution. More than a half-century later, we are still delivering on that mission. NCAR provides the atmospheric and related Earth system science community with state-of-the-art resources, including supercomputers, research aircraft, sophisticated computer models, and extensive data sets. From its founding, NCAR was meant to provide the atmospheric research community with the shared resources necessary to work on the most important scientific problems of the day. Not much has changed. The hundreds of scientists who work here research all things atmospheric — which includes everything from the microphysics of cloud formation and the chemistry of air pollution to large-scale planetary waves and the impact of increased greenhouse gases on our climate. Since the atmosphere interacts with everything it touches, its crucial to investigate those interactions, too.

The ODIS "Catalogue of Sources" aims to be an online browsable and searchable catalogue of existing ocean related web-based sources/systems of data and information as well as products and services. It will also provide information on products and visualize the landscape (entities and their connections) of ocean data and information sources. It will contribute to the objectives of the Agenda 2030, and in particular the UN Decade for Ocean Science for Sustainable Development. The Catalogue is not an ocean database or metadata repository. The catalogue includes descriptive information such as the URL, title, description, language, point of contact, geographic scope, available technologies for machine-to-machine interaction, keywords, etc. and can be searched on many of these fields. The IODE network of NODCs has been collecting, managing and serving data for decades. This effort has yielded an extensive, but distributed and heterogeneous collection of data and information sources. Additionally, the low threshold for technical capabilities required to offer data and information over the Internet means that many of the hosted resources are not readily discoverable through NODCs, regional or international data and information systems ODIS will provide an online catalogue of (ideally) all online data/information sources (and, where possible, metadata on off-line sources as well). Many regional and international programmes and projects have developed online data/information services but there is currently no "one-stop shop" where users are offered an overview and/or common data/information discovery interface. There are currently 3090 sources (2172 are searchable) catalogued in the system.

Stakeholder networks from 32 countries united to collaborate on Ocean Action, Climate Action, addressing pollution from land-based, riverine and marine-based sources and advancing Circular Economy development. International Waste Platform provides international expertise and launches joint initiatives; It supports advancing solutions to mitigate the global waste, plastic pollution & climate crises which are interlinked. Representatives committed themselves to align objectives, to support the implementation of strategies of Ocean Action and Climate Action, as well as to share ideas, best practices, concepts, programs, knowledge and opportunities; including the reduction of plastic debris at the source, before it enters rivers and the coastal environment. Country / regional networks and national marine debris networks make a difference in societal behaviour change and environmental policies by providing input and promoting action which aims at finding solutions to reduce (ocean) plastic pollution. Country and regional networks are instrumental to reach the prevention and reduction of marine pollution, facilitate and foster the establishment of national and international partnerships in a multi-stakeholder approach.

Seabed Habitats was one of seven themes of the European Marine Observation and Data Network (EMODnet) initiative, funded by the European Maritime and Fisheries Fund. Since its inception in 2009, EMODnet Seabed Habitats developed, improved and gradually increased the coverage of a broad-scale seabed habitat map for Europe's seabed, also known as EUSeaMap. In addition, EMODnet Seabed Habitats continued the work started by MESH and MESH Atlantic projects in collating and making available seabed habitat maps from surveys, through the EMODnet Seabed Habitats map viewer. In it's third Phase (2017-2019), EMODnet Seabed Habitats collated and provided habitat point data and the outputs of habitat distribution modelling, and the third phase has now been extended to 2021. The extended third phase of the project will: - Continue to grow Europe's only comprehensive library of habitat maps from surveys and collection of survey sample points - Create new composite data products to add to those for the Essential Ocean Variable habitats and OSPAR threatened and/or declining habitats - Update the EMODnet broad-scale seabed habitat map for Europe (EUSeaMap) using the next seabed substrate update from EMODnet Geology - Update web content with extra resources for habitat mapping, including a catalogue highlighting all the most useful data products

Marine data sharing and preservation, managed & operated by the National Oceanography Centre. Part of the UK's National Oceanography Centre, BODC provide instant access to over 130,000 unique data sets. BODC data helps provide answers to both local questions such as the likelihood of coastal flooding, or global issues such as the impact of climate change. Data categories include: - Acoustics - Bathymetry and topography - Currents — horizontal and vertical velocity, Lagrangian currents and water transport rates - Meteorology — Radiosonde, Met. stations and data buoys - Optical properties — pigments, turbidity, irradiance - Sea level - Water column temperature and salinity - Water column chemistry — nutrients, carbons, oxygen - Waves — statistics and spectra

EMODnet Biology provides three keys services and products to users. 1)The data download toolbox allows users to explore available datasets searching by source, geographical area, and/or time period. Datasets can be narrowed down using a taxonomic criteria, whether by species group (e.g. benthos, fish, algae, pigments) or by both scientific and common name. 2) The data catalogue is the easiest way to access nearly 1000 datasets available through EMODnet Biology. Datasets can be filtered by multiple parameters via the advanced search from taxon, to institute, to geographic region. Each of the resulting datasets then links to a detailed fact sheet containing a link to original data provider, recommended citation, policy and other relevant information. Data Products - EMODnet Biology combines different data from datasets with overlapping geographic scope and produces dynamic maps of selected species abundance. The first products are already available and they focus on species whose data records are most complete and span for a longer term.

Several climate indices, regarding Atlantic Basin: - North Atlantic Oscillation - Southern Oscillation Index - Bivariate ENSO Timeseries - Tropical Northern Atlantic Index - Tropical Southern Atlantic Index - Oceanic Niño Index - Multivariate ENSO Index (MEI V2) - North Tropical Atlantic SST Index - ENSO precipitation index - Northeast Brazil Rainfall Anomaly - Solar Flux (10.7cm) - Global Mean Lan/Ocean Temperature

The Western Channel Observatory (WCO) is an oceanographic time-series and marine biodiversity reference site in the Western English Channel. In situ measurements are undertaken weekly at coastal station L4 and fortnightly at open shelf station E1 using the research vessels of the Plymouth Marine Laboratory and the Marine Biological Association. These measurements are complemented by PML's recognised excellence in ecosystem modelling and satellite remote sensing science. By integrating these different observational disciplines we can begin to disentangle the complexity of the marine ecosystem. The WCO measures several key parameters important to the functioning of the marine ecosystem such as light, temperature, salinity and nutrients. Station L4 has some of the longest time-series in the world for zooplankton and phytoplankton, and fish trawls have been made by the MBA for a century. Station E1 has a hydrographic series dating from 1903. These long series are complemented by hourly measurements made at our moorings situated at both stations. These can elucidate changes not captured by the routine weekly sampling.

NASA's Physical Oceanography Distributed Active Archive Center (PO.DAAC) is located at NASA's Jet Propulsion Laboratory in Pasadena, California. PO.DAAC manages and provides tools and services for NASA's oceanographic and hydrologic data (satellite, airborne, and in-situ) to enable a greater understanding of the physical processes and conditions of the global ocean. Measurements include gravity, ocean winds, sea surface temperature, ocean surface topography, sea surface salinity, and circulation. The data support a wide range of applications including climate research, weather prediction, resource management, policy, and the stewardship of ocean data resources.
