Coral reefs are one of the most diverse and ecologically important areas of the world. However, many reefs, are threatened by ocean temperatures that are increasingly becoming warmer than the coral animals' natural tolerance. According to NOAA, when water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
 

The NOAA Coral Reef Watch program uses satellite data to provide current reef environmental conditions to quickly identify areas at risk for coral bleaching. The station data displayed in this map are derived from satellite based measurements of ocean temperature. These \"virtual stations\" are not actual buoys or in situ stations transmitting data, rather a spatial analyses for reef locations around the world are derived from 5 km resolution raster data. 

 
There are 213 points for the virtual stations around the world along with polygons describing the major tropical coral reef systems.

The World Database on Protected and Conserved Areas (WDPCA) is a joint product of UNEP and IUCN, managed by UNEP-WCMC, working with governments and other data providers. The database stores information on the global distribution of terrestrial, inland water and marine protected areas and other effective area-based conservation measures (OECMs). The WDPCA combines the formerly separate World Database on Protected Areas (WDPA) and World Database on Other Effective Area-based Conservation Measures (WD-OECM).

\n\n

The database contains data on protected areas and OECMs designated at the national level and under regional and international conventions and agreements, in addition to those recognised through other means. The WDPCA adopts the definitions of a protected area used by IUCN and the Convention on Biological Diversity (CBD), and the definition of an OECM adopted by Parties to the CBD.

\n\n

A User Manual (UNEP-WCMC 2026) is provided with the dataset. This includes a description of the attribute table and guide to interpreting its fields. The WDPCA can be viewed at, and downloaded from, Protected Planet (https://www.protectedplanet.net/) or from IBAT for commercial purposes (https://www.ibat-alliance.org/).

\n\n

A new version is published each month. The latest version is available from https://www.protectedplanet.net/.

The hillshading is based on a solar altitude angle of 45 degrees, and solar aspect angle of 315 degrees. The z factor is varied based on scale so that a suitable hillshade is visible at all scales.

*** The funding for the Anti-shipping Activity Messages (ASAM) database ended in June 30, 2024; as a result we are no longer updating the ASAM database or the GIS data on our web page. The Office of Naval Intelligence does have PDF files of ASAM events on their Worldwide Threat to Shipping page - https://www.oni.navy.mil/ONI-Reports/Shipping-Threat-Reports/Worldwide-Threat-to-Shipping/ [oni.navy.mil]. ***
 

The United Nations Convention on the Law of the Sea (UNCLOS) defines \"Piracy\" and: 

(a) any illegal acts of violence or detention, or any act of depredation, committed for private ends by the crew or the passengers of a private ship or a private aircraft, and directed: 
(i) on the high seas, against another ship or aircraft, or against persons or property on board such ship or aircraft; 
(ii) against a ship, aircraft, persons or property in a place outside the jurisdiction of any State; 

(b) any act of voluntary participation in the operation of a ship or of an aircraft with knowledge of facts making it a pirate ship or aircraft; 

(c) any act of inciting or of intentionally facilitating an act described in subparagraph (a) or (b).

Pirate attacks affect many different parties, including the flag state of the vessel that is attacked, the states of nationality of the crew members aboard the attacked vessel, the state from which the pirates originate, the state in whose waters (if any) the attack occurs, the states of the ship and cargo owners, and the states for which cargo on attacked vessels is destined. In addition to their immediate impacts on the vessels, individuals, and cargo involved in an attack, sustained episodes of piracy can affect international shipping rates (by leading to the diversion of cargoes to other shipping lanes) and lead to increases in insurance rates. Further, they can isolate those states from which the piracy is originating if vessels refuse to make port calls in those nations.

Anti-shipping Activity Messages (ASAM) include the locations and descriptive accounts of specific hostile acts against ships and mariners. The reports may be useful for recognition, prevention and avoidance of potential hostile activity.

This layer can be searched using ASAM reference number(s), sub region, or occurrence date(s). Each record includes the date of occurrence, an ASAM reference number, the number identifying the geographical subregion, the latitude and longitude of the geographical location, the aggressor if known, the type of vessel victimized, the name of the vessel victimized and a detailed description of the occurrence.

The map is designed to be used as a basemap by marine GIS professionals and as a reference map by anyone interested in ocean data. The basemap focuses on bathymetry. It also includes inland waters and roads, overlaid on land cover and shaded relief imagery.

 
The Ocean Base map currently provides coverage for the world down to a scale of ~1:577k; coverage down to ~1:72k in United States coastal areas and various other areas; and coverage down to ~1:9k in limited regional areas.
 
The World Ocean Reference is designed to be drawn on top of this map and provides selected city labels throughout the world. This web map lets you view the World Ocean Base with the Reference service drawn on top. Article in the Fall 2011 ArcUser about this basemap: \"A Foundation for Ocean GIS\".
 
The map was compiled from a variety of best available sources from several data providers, including General Bathymetric Chart of the Oceans GEBCO_08 Grid version 20100927 and IHO-IOC GEBCO Gazetteer of Undersea Feature Names August 2010 version (https://www.gebco.net), National Oceanic and Atmospheric Administration (NOAA) and National Geographic for the oceans; and Garmin, and Esri for topographic content. You can contribute your bathymetric data to this service and have it served by Esri for the benefit of the Ocean GIS community. For details on the users who contributed bathymetric data for this map via the Community Maps Program, view the list of Contributors for the Ocean Basemap. The basemap was designed and developed by Esri. 
 
The GEBCO_08 Grid is largely based on a database of ship-track soundings with interpolation between soundings guided by satellite-derived gravity data. In some areas, data from existing grids are included. The GEBCO_08 Grid does not contain detailed information in shallower water areas, information concerning the generation of the grid can be found on GEBCO's website: https://www.gebco.net/data_and_products/gridded_bathymetry_data/. The GEBCO_08 Grid is accompanied by a Source Identifier (SID) Grid which indicates which cells in the GEBCO_08 Grid are based on soundings or existing grids and which have been interpolated. The latest version of both grids and accompanying documentation is available to download, on behalf of GEBCO, from the British Oceanographic Data Centre (BODC) https://www.bodc.ac.uk/data/hosted_data_systems/gebco_gridded_bathymetry_data/.

This resource was developed by the U.S. Geological Survey (USGS) in partnership with Esri and the Marine Biodiversity Observation Network (MBON). These data were developed as part of a Group on Earth Observations (GEO) initiative called GEO Ecosystems (GEO ECO), and is associated with a GEO ECO task to develop global coastal ecosystems data. The data allows for the visualization and query of any stretch of coastline on Earth, except for Antarctica. The underlying data are 4 million 1 km or shorter coastal segments, each of which is attributed with values from ten ecological settings variables representing the adjacent ocean, the adjacent land, and the coastline itself.

The 4 million coastal segments were classified into 81,000 coastal segment units (CSUs) using the Coastal and Marine Ecosystem Classification Standard (CMECS). Each distinct CSU is a segment with a unique combination of the classes of values of the ten ecological settings variables. The 4 million segments were also clustered into a set of 16 global groups of coastlines which are similar in the aggregate ecological setting described by the ten variables.

See this video for an animation showing ECU coverage and classification.

The concentration of dissolved gases in water is of prime importance in considering the quality of water. Sufficient amounts of dissolved oxygen are required for marine-life survival. Dissolved oxygen levels are influenced by temperature and salinity.The ability for oxygen to dissolve in water (solubility) decreases as temperature and salinity increase. Poorly oxygenated areas, or those with a dissolved oxygen level below 1, are considered dead zones or hypoxic zones. Dissolved oxygen is carried to the deep-sea floor by the descending surface waters.

http://www.aoml.noaa.gov/phod/dac/dac_meanvel.php

Satellite-tracked SVP drifting buoys (Sybrandy and Niiler, 1991; Niiler, 2001) provide observations of near-surface circulation at unprecedented resolution. In September 2005, the Global Drifter Array became the first fully realized component of the Global Ocean Observing System when it reached an array size of 1250 drifters. A drifter is composed of a surface float which includes a transmitter to relay data, a thermometer that reads temperature a few centimeters below the air/sea interface, and a submergence sensor used to detect when/if the drogue is lost. The surface float is tethered to a holey sock drogue, centered at 15 m depth. The drifter follows the flow integrated over the drogue depth, although some slip with respect to this motion is associated with direct wind forcing (Niiler and Paduan, 1995). This slip is greatly enhanced in drifters that have lost their drogues (Pazan and Niiler, 2000). Drifter velocities are derived from finite differences of their position fixes. These velocities, and the concurrent SST measurements, are archived at AOML's Drifting Buoy Data Assembly Center where the data are quality controlled and interpolated to 1/4-day intervals (Hansen and Herman, 1989; Hansen and Poulain, 1996).

In this study, 6h winds were interpolated onto the drifter positions and used to estimate and remove the slip (Niiler and Paduan, 1995; Pazan and Niiler, 2000; Laurindo et al., 2017). All velocities and SSTs were lowpassed at 1.5 times the local inertial period, or five days if that is smaller, to remove high frequency variability (diurnal, tidal, inertial). If 1.5 times the local inertial period is shorter than one day, the lowpass is done at one day.

Drifters sample regions of the ocean inhomogeneously, which can cause aliased time-mean values if strong seasonal or interannual variations are neglected. To address the seasonal cycle, Lumpkin (2003) developed a methodology to simultaneously decompose the drifter observations into time-mean, seasonal and eddy components using a Gauss-Markov approach that produces formal error bars on all components. Lumpkin showed that this methodology produces significantly different results than standard bin averaging. This methodology was further developed and evaluated using SST observations and products, and simulated drifters in the MICOM model (Lumpkin and Garraffo, 2005). The method produces significantly improved estimates of the mean currents and SST, and simultaneously provides the annual and semiannual amplitudes and phases at a nominal resolution of one degree squared.

To address inhomogeneous interannual sampling associated with ENSO, Johnson (2001) added a component proportional to a five-month lowpassed Southern Oscillation Index, and estimated components in elliptical bins with axes scaled and oriented using the residual variability (i.e., the eddy fluctuations).

In Lumpkin and Johnson (2013), the methodologies of Lumpkin (2003) and Johnson (2001) are combined. The observations are projected onto a time mean, annual and semiannual, SOI, and spatial gradient components within elliptical bins scaled and oriented using eddy fluctuations, and error bars are estimated for all terms.

In Laurindo et al. (2017), slip correction using a spatially-varying coefficient was introduced in order to exploit velocity information from undrogued drifters. This approximately doubles the number of available observations, which allowed the bin sizes to be considerably reduced (one degree radius circles). In addition, 1D spatial fitting was done in the direction that maximizes the explained variance, allowing for greater resolution of cross-stream velocity gradient. These two changes result in significantly better spatial resolution of ocean current structure. In addition, Laurindo et al. examined how the formal standard errors compare to actual errors when using a "toy" dataset of surface currents derived from AVISO and subsampled at the drifter observation locations and times; they found that formals errors underestimate actual errors by approximately a factor of 2.

When these more advanced methodologies are applied to the modern data set of tropical Atlantic drifter observations, many features of the near-surface circulation become apparent which were not resolved by older ship-drift-based climatologies or by SEQUAL/FOCAL drifter trajectories (Lumpkin and Garzoli, 2005). In the Hawaiian Island region, the thousand-kilometer long island wake is revealed at unprecedented detail (Lumpkin and Flament, 2013) Zonally elongated mid-ocean striations are resolved in the zonal currents of all major ocean basins (Laurindo et al., 2017).

Daily Chlorophyll-a concentration (0.01 to 50 mg/m-2) at 4.6 km (at the equator) resolution.  Chlorophyll in water changes the way it reflects and absorbs sunlight, allowing scientists to map the amount and location of phytoplankton using optics. These measurements give scientists valuable insights into the health of the ocean environment, and help scientists study the ocean carbon cycle. Subtle changes in chlorophyll-a signify various types and quantities of marine phytoplankton (microscopic marine plants), the knowledge of which has both scientific and practical applications.

These chlorophyll layers show milligrams of chlorophyll per cubic meter of seawater. Places where chlorophyll amounts were very low, indicating very low numbers of phytoplankton are blue. Places where chlorophyll concentrations were high, meaning many phytoplankton were growing, are dark green. The observations come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite.  Places where MODIS could not collect data because of sea ice, polar darkness, or clouds are masked.

The MODIS instrument is managed by NASA/Goddard Space Flight Center, Greenbelt, Maryland and was built by Raytheon/Santa Barbara Remote Sensing, Goleta, California. For further information, access the MODIS Homepage at modis.gsfc.nasa.gov

Argo is a global network of more than 3000 free-drifting robots that measure temperature and salinity of the upper 2000 m of the ocean. This allows, for the first time, continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being sent to satellites passing overhead and then made publicly available within hours after collection.



Main Benefits:


     - Improve Ocean and Climate forecasting

     - Understand ocean-atmosphere interactions

     - Predict seasonal to decadal climate variability



Argo improves maps of the distribution of the heat energy in the ocean and, as a consequence, improves forecasting of the development (track and intensity) of sever weather systems. Sever weather systems are driven by convection and the transfer of water vapour from the ocean to the atmosphere.

Argo is a global network of more than 3000 free-drifting robots that measure temperature and salinity of the upper 2000 m of the ocean. This allows, for the first time, continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being sent to satellites passing overhead and then made publicly available within hours after collection.



Main Benefits:


     - Improve Ocean and Climate forecasting

     - Understand ocean-atmosphere interactions

     - Predict seasonal to decadal climate variability



Argo improves maps of the distribution of the heat energy in the ocean and, as a consequence, improves forecasting of the development (track and intensity) of sever weather systems. Sever weather systems are driven by convection and the transfer of water vapour from the ocean to the atmosphere. Hurricanes (e.g. Katrina, Gulf of Mexico) gain strength when passing over positive temperature anomaly areas and decay over low temperature anomaly regions. Argo, an old dream of oceanographers, is becoming the ocean's climate warning system for the benefits of humankind.
