Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico (2015 Version) Abstract Cetaceans are protected worldwide but vulnerable to incidental harm from an expanding array of human activities at sea.

Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico (2015 Version)

Managing potential hazards to these highly-mobile populations increasingly requires a detailed understanding of their seasonal distributions and habitats. Pursuant to the urgent need for this knowledge in U.S. waters of the western North Atlantic and Gulf of Mexico, we integrated aerial and shipboard cetacean surveys conducted by five scientific organizations over 23 years and linked them to environmental data relating to cetacean habitat, such as sea surface temperature and chlorophyll concentration, obtained from satellite remote sensing and ocean models. Using distance sampling methodology, we built statistical models of cetacean density—the number of individual animals found per square kilometer of area—from environmental variables for 26 species and 3 multi-species guilds, and produced maps showing average density across the modeled region.

International Trade Statistics Database. Marine Gravity from Satellite Altimetry. Data on slight variations of the pull of gravity over the oceans are recorded with satellite altimetry, and are then combined to map the seafloor globally.

Free mapping data will elevate flood risk knowledge. For the past 17 years we have been capturing LIDAR (Light Detection & Ranging) data in England.

LIDAR uses a laser to scan and map the landscape from above and is widely considered to be the best method for collecting very dense and accurate elevation data across the landscape. We use LIDAR to help the work of the Environment Agency in many ways, including creating flood models, assessing coastal change and analysing how land is used.

Les prévisions océanographiques de référence sur data.shom.fr

Ses données de prévisions océanographiques sont issues de modèles développés avec de nombreux partenaires scientifiques et institutionnels ( et notamment). Ces données à très haute résolution spatiale et temporelle sont désormais disponibles sur le portail data.shom.fr. data.shom.fr permet d’afficher les prévisions, jusqu’à 5 jours, des paramètres décrivant les mers et océans : - température de la mer, - salinité, - courants marins, - vagues, en Manche, dans le golfe de Gascogne et en Méditerranée. Ces prévisions sont nécessaires à la protection et à la mise en valeur de la mer, à la prévention des risques, au développement durable des activités en mer, à la planification de l’espace maritime, à l’aménagement littoral, et à l’étude du changement climatique.

Data is produced on a project specific basis, but when time and feasibility allows, we try and extend analyses to the greatest spatial and temporal extent possible to allow the greatest applicability to other projects as well. In the broadest sense, our data extends from the mid–1800s to 2100, across multiple spatial extents including: Alaska, Alaska-Western Canada, Polar, and worldwide. The list of variables is always expanding, so please explore below to see what we currently have available. Natural Spaces - Scottish Natural Heritage.

This is a flashback post, I was working on species distribution shifts over the last 40 years last summer and recently Rémi Genevest contacted me asking me how I managed to import the CRU TS 1.2 dataset into R.

As always a more readable version of the code can be found here. At that time I used a not very elegant coding involving SpatialPixels and SpatilGridDataFrame, scrolling back to the question I asked to the R-sig-geo mailing list back then I stumbles across the answer from Robert Hijmans that I did not take into account at that time.

In May 2013, Google’s vice president took to stage and announced that Google was aiming to build “a perfect map of the world.” An honorable notion with almost utopian connotations — and why shouldn’t it? After all, Google has been at the forefront of leading the biggest change to mapping since the 15th century, when maps went from manuscript to print. Now they’re online and taking advantage of satellite imagery, maps are more detailed, accurate and multi-dimensional than they’ve ever been, but could such a thing as the perfect map ever exist?

The dark side of data. A few weeks ago, Tom Slee published “Seeing Like a Geek,” a thoughtful article on the dark side of open data.

He starts with the story of a Dalit community in India, whose land was transferred to a group of higher cast Mudaliars through bureaucratic manipulation under the guise of standardizing and digitizing property records. While this sounds like a good idea, it gave a wealthier, more powerful group a chance to erase older, traditional records that hadn’t been properly codified.

One effect of passing laws requiring standardized, digital data is to marginalize all data that can’t be standardized or digitized, and to marginalize the people who don’t control the process of standardization. That’s a serious problem. It’s sad to see oppression and property theft riding in under the guise of transparency and openness. MIT geospatial.
