As a boater or marina operator, you have probably experienced first-hand the effects of pollutants. Although you may make every feasible effort to prevent pollutants from entering your local waters, not all sources are easy to pinpoint. Here is a quick refresher of some of the most common types and sources of contaminants.
Most pollution can be categorized as “point” or “nonpoint” discharges. Point sources of pollution – such as outfall pipes – introduce pollution into the environment at a specific site or point. They are generally the easiest to identify, monitor and regulate.
By contrast, nonpoint source pollution comes from a plethora of diffuse sources and is unconstrained in movement. Nonpoint source pollution is caused by water (typically rainfall or snowmelt) moving over and through the ground. Sources include storm drains and runoff from parking lots, roadways or agricultural land.
Looking for some extra motivation to keep that resolution to go to the gym? How about saving the planet? It’s easy to incorporate small changes into your workout routine that will actually benefit our ocean’s health.
Here are four ways you can help keep the ocean healthy while working toward a healthier you: Continue reading »

So back in 1992 when Hilberto Riverol, national scout executive with the association, heard that the Ramada Hotel in Belize City was gathering volunteers for the country’s first International Coastal Cleanup, he signed up. Some 600 participants including the scouts removed more than three tons of trash from approximately 18 miles of the coast. Continue reading »
What if you could take the pulse of the ocean? What if that measure could integrate all the threats and impacts to the ocean, rather than evaluating each one separately? And instead of dwelling on these negatives, the metric could express the health of the ocean by quantifying and adding up the most important ways the ocean benefits humans. Most importantly, the measure wouldn’t portray humans as separate from nature, but rather embed us deeply in this “seascape” and empower us – all of us – to chart a course for the future of the ocean.
The newly released Ocean Health Index (OHI) may very well get us there. The OHI takes on the big issues – pollution, habitat destruction, invasive species, fishing and climate change – and its findings should cause us all to think hard about what we want the ocean to provide. The short story is that the global ocean scores 60 out of a possible 100 points, with large variation among the 171 countries and territories evaluated. Whether you view the glass as half empty or half full, there is clearly considerable room for improvement. Continue reading »
What does a healthy ocean look like? The Ocean Index brings together scientific data on everything from coral to the economics of coastal communities to answer this critical question. Credit: Arthur Koch
At Ocean Conservancy, we often get asked “How is the ocean doing?” That straightforward question is actually quite difficult to answer. This vast resource, our planet’s life support system, faces many complex challenges. Quantifying them is no easy matter.
The new Ocean Index announced in Nature is one way to assess and compare the health of ocean ecosystems across different countries. To date, there’s been no comprehensive source that brings together all manner of ocean-related research in one place. The Index is a good starting point.
Sixty-five scientists and other experts worked together to create this tool. They use a series of indicators to measure ten goals important to us all, including
The Index looks at the current status for each, as well as the likely scenario for sustainability into the future. Overall, the health of the ocean received a score of 60 out of 100. The United States is in the middle of the pack with a score of 63. Continue reading »
