What is the Cumulative Impact of Human Activity on the World’s Oceans?

Cumulative Impacts of Human Activity on the Oceans

Have you ever wondered what the impact is of human activity on the world’s oceans?

In short, a lot.

This animation shows the cumulative impacts of human activity on the oceans. Green represents areas with less impact, and red represents areas that experience much greater impact.

A study by Dr. Kenneth Casey in Feb 2008 , with NOAA’s National Oceanographic Data Center, shows that 40% of the world’s oceans are heavily affected by human activities like overfishing and pollution. The marine ecosystems most threatened by human activities are coral reefs.

The ocean impacts the lives of everyone on Earth, even those who do not live on or near the coast, and humans affect the ocean in a variety of ways. Individual and collective action is necessary to wisely manage ocean resources for all.

Which areas have been impacted the most?
What about the least?

Did you view the actual animation? If so, what surprised you about human’s impact on the world’s oceans? What did not surprise you?

Need a Heterogeneous Digital Preservation Solution?

Are you looking for a digital preservation solution that is open source but not one-size-fits-all? Then check out the tools of the Scalable Preservation Environments (SCAPE) Project, an EU funded digital initiative.

The SCAPE project develops scalable services for planning and execution of institutional preservation strategies on an open source platform that orchestrates semi-automated workflows for large-scale, heterogeneous collections of complex digital objects. SCAPE will enhance the state of the art of digital preservation in three ways: by developing infrastructure and tools for scalable preservation actions; by providing a framework for automated, quality-assured preservation workflows, and by integrating these components with a policy-based preservation planning and watch system. These concrete project results are being validated within four large-scale Testbeds from diverse application areas.

I like the policy-based preservation aspect of this system. That is my area of research for my dissertation.

Are there any particular aspects of this project that caught your attention?

Animation of the TransAtlantic Flight Paths of Over 2000 Airplanes

Here’s a relaxing video and soundtrack to start off your Monday.



An animation by the National Air Traffic Services (Nats), the UK air traffic control service, demonstrates the flight paths of the 2,000 to 3,000 aircraft that fly across the North Atlantic on a daily basis. This animation shows 2,524 flights that travelled between Canada, the US and Europe on a single day in August 2013

Of course, knowing that many airplanes are in the air at any given time of the day may not be your idea of relaxation. However…Happy Monday!
