The 2010 BP Deepwater Horizon oil disaster in the Gulf of Mexico revealed a challenge with the way scientific monitoring information is shared and stored.

At the time, the scientific records of monitoring efforts in the Gulf of Mexico was dispersed across many entities from universities, natural resource management agencies, private industries to non-governmental organizations. In most cases monitoring systems were developed independently, often narrowed to specific questions, such as how many oysters should be harvested and how many should be left in the water?

Monitoring systems are rarely coordinated across states and other agencies, and the scattered nature of these information systems makes it difficult for any one group of scientists or organizations to find and access the full expanse of data available.

To help address this issue Ocean Conservancy produced the 2015 report Charting the Gulf: Analyzing the Gaps in Long-term Monitoring of the Gulf of Mexico. The report compiles an extended inventory of nearly 700 past and existing long-term monitoring efforts in the Gulf. Ocean Conservancy’s goal was to provide scientists, academics and restoration decision-makers with a cohesive inventory that could save time and money when planning monitoring for restoration projects or programs.

Recently, NOAA’s Office of Response and Restoration, charged with supporting science information needs during oil spills, began hosting Ocean Conservancy’s inventory of monitoring programs through NOAA’s map-based Gulf of Mexico Environmental Response Management Application (ERMA). Combining this monitoring data with ERMA is a great step towards creating sustained visibility of existing data sources in the Gulf.

“Ocean Conservancy’s gap analysis of long-term monitoring programs in the Gulf of Mexico will serve as a valuable resource for the NRDA Trustees as they plan, implement, and monitor restoration progress in the Gulf of Mexico over the next 25 years,” said Melissa Carle, Monitoring and Adaptive Management Coordinator, Deepwater Horizon Restoration Program.

The new gap analysis dataset in ERMA will allow trustees to visualize the footprint of existing monitoring programs, assisting in the identification and prioritization of gaps that impact planning restoration actions and evaluate restoration progress for the habitats and resources injured by the spill.

Is There a New Species of Whale in the Gulf of Mexico? http://blog.oceanconservancy.org/2013/04/05/is-there-a-new-species-of-whale-in-the-gulf-of-mexico/ http://blog.oceanconservancy.org/2013/04/05/is-there-a-new-species-of-whale-in-the-gulf-of-mexico/#comments Fri, 05 Apr 2013 20:17:51 +0000 Alexis Baldera http://blog.oceanconservancy.org/?p=5346

The tan color on this map shows the range of sperm whales in the Gulf of Mexico. The colored areas show the chance of sperm whales utilizing this habitat, with red being the highest.

Not quite a new species, but the population of sperm whales in the Gulf is distinctly different from their relatives. So different that last week, in response to a petition from WildEarth Guardians, the National Marine Fisheries Service announced that it will be taking a closer look at sperm whales in the Gulf of Mexico in order to determine if they should be protected under the Endangered Species Act. Sperm whales across the world are already listed as an endangered species, but this new designation will recognize the Gulf population as a distinct group and protect and monitor it separately from the global population.

There are characteristics of sperm whales in the Gulf that may be sufficient to classify them as a distinct group. Gulf sperm whales do not leave the Gulf and are generally smaller and use  different vocalizations (probably learned culturally) than other sperm whales. Gulf sperm whales also face Gulf-specific threats such as oil and gas development, high levels of shipping traffic and noise, potential effects from the BP Deepwater Horizon oil spill, and water quality degradation near the mouth of the Mississippi River. As shown on the map above, the area southeast of the Mississippi River Delta is important for sperm whales. The outflow of nutrients from the river, upwelling along the continental slope and eddies from Gulf currents create unique ecological conditions that make this a productive area where sperm whales go to find food and potentially mates.

We do not know whether the population of sperm whales in the Gulf is growing or declining, or how many human-caused deaths of sperm whales happen in the Gulf. In order to improve our understanding of this amazing species, which is so dependent on the Gulf, we need more long-term research and monitoring. One way to gather information about sperm whales, and other marine mammals, is through tagging and tracking of the animals. Using satellite-linked tags and radio transmitters attached to animals can provide information on habitat use, foraging behavior, distribution and exposure to hydrocarbons. Ocean Conservancy is working to enhance marine mammal tracking and tagging research in the Gulf. We are proposing that some restoration funding from the BP Deepwater Horizon oil spill be allocated to tracking and tagging research for marine animals in the Gulf to increase our understanding of these animals and their threats.

Tagging and tracking wildlife over time will put scientists in a much stronger position to learn whether or where changes are happening in the Gulf, and to make sure we are on the right course to recovering from the nation’s largest offshore environmental crisis.
