To the Point (and Nonpoint): Understanding Sewage Pollution and Stormwater Runoff

Posted On June 3, 2015 by

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.

Red Snapper Season Starts June 1: Not All Smooth Sailing

Posted On May 29, 2015 by

Anglers all over the Gulf of Mexico will spend their weekend getting ready for Monday, June 1,  the first day of the 2015 Gulf of Mexico recreational red snapper fishing season. Thanks to the hard work of fishermen, managers and the Magnuson-Stevens Fishery Conservation and Management Act, fishermen will be able to catch more red snapper this year than the past 8 years.  While we are seeing increases in the allowable catch of red snapper, recreational fishermen have witnessed red snapper fishing seasons shrink year after year. This year the private boat-owning public can fish for a short 10 days while anglers fishing with charter-for-hire captains get 44 days. The charter-for-hire season is a solid increase over the 2014 season, which allowed only 9 fishing days for both components of the recreational fishing sector, but the short 10-day private recreational remains problematic. While there is no arguing that the longer charter-for-hire fleet is fantastic news for captains and their charters, the short private boat-owner’s season illustrates the need for management innovation for the private recreational fishing component that will help anglers access and enjoy the fruits of a healthy and growing Gulf red snapper population.

Across the Gulf; Saving Sea Turtles in Tecolutla, Mexico

Posted On May 26, 2015 by

Hello! My name is Jessica Miller. I am an undergraduate at the University of South Carolina, where I just completed my sophomore year. I am majoring in biology and I intend to eventually pursue a career in research. Growing up in a small town in South Carolina, I developed a deep interest in science and knew I wanted to do something with animals. This summer I am traveling to Mexico to participate in an amazing study abroad program that will help with the conservation of endangered Kemp’s Ridley sea turtles, as well as provide valuable information on the degree of marine debris found in the area.

On May 8th, I traveled to Mexico for the first time in my life. While many people travel to the country to explore the sites and relax on the beaches, my intentions are slightly different. I have an awesome opportunity to conduct research with several other students in my study abroad program. What exactly is it that we will be researching? Sea turtles, of course! More specifically, the primary focus of my voyage is the conservation of the Kemp’s Ridley sea turtle. These turtles are endangered and quite unique as well.

Kemp’s ridley sea turtles are relatively small by sea turtle standards. They usually only grow to be about 3 feet long with a shell that is about 2 feet long. They are also one of the few sea turtles to nest during the day. Kemp’s ridley sea turtles also have a limited nesting habitat. They only nest along the Gulf of Mexico, which highlights one of the many reasons the Gulf is so important; and why the condition of its beaches is so important as home to a variety of marine organisms that do not exist anywhere else. More information on the Kemp’s ridley sea turtles, along with other work being done in Tecolutla, can be found at the Tecolutla Turtle Preservation Project.

Santa Barbara Oil Spill Jeopardizes the Golden Beaches of Our Golden State

Posted On May 21, 2015 by

When oil began flowing from a ruptured pipeline along the wild and scenic shoreline up the coast from Santa Barbara, California, the community’s coastal life flashed before its eyes:  thriving fisheries, popular and pristine beaches, teeming populations of whales and marine mammals, and a new network of protected areas set up to safeguard these coastal treasures.  The awful images of oiled beaches and sea life are appearing on our screens at a time when visitors are flocking to the coast for Memorial Day weekend.

Recreational and commercial fishing have been ordered closed in the wake of the spill. Fishing grounds along the rural coast west of Santa Barbara support a good deal of the harvest of some of California’s highest-value fisheries. Spiny lobster, red sea urchin and market squid are harvested along this coastline, and are among the top five commercial fisheries in California, bringing in millions of dollars in revenue from the sale of fish and providing healthy seafood for local and distant consumers. Recreational fishermen ply these waters for calico bass, white seabass and halibut while enjoying the scenic surroundings and spending dollars locally. Surfers, scuba divers, beachgoers and whale watchers explore, play and spend in even greater numbers.

The 2014 International Coastal Cleanup Data Are In

Posted On May 19, 2015 by

Another year, another incredible volunteer effort—I’m excited to share with you today the findings from last year’s International Coastal Cleanup. In 2014, more than 560,000 people picked up more than 16 million pounds of trash along nearly 13,000 miles of coastlines. Thank you to all the volunteers, Coordinators and partners who participated and devoted countless hours and resources!

Last year’s Cleanup had the largest weight of trash collected during any Ocean Conservancy Cleanup since its inception 29 years ago. Volunteers from 91 countries gathered detailed information from their Cleanups to provide a snapshot of the most persistent forms of trash found along the beaches and waterways that’s impacting our ocean.

This data represents what was found at the 29th Cleanup – each and every year hundreds of thousands of volunteers step up to meet the challenge and help clean up the beaches and waterways in their communities. There’s no doubt in my mind – as the Cleanup report will show you – the unparalleled effort of volunteers around the world results in cleaner beaches, rivers and lakes for all to enjoy.

Making Even Better Decisions About Sea Scallop Harvests

Posted On May 7, 2015 by

How do you like to make big, complicated decisions? I like to write lists of pros and cons associated with the choice I’m leaning towards. That’s served me well for changing jobs, selling houses and more.

But for complex systems, like fisheries, simply comparing pros and cons of one choice isn’t enough. There are many moving parts in a fishery, and they are interconnected. For example, when fishermen harvest sea scallops, they reduce the overall number of scallops in an area, and change the age and size distribution of individual scallops. At the same time, factors like rising water temperature, availability of food, or quality of habitat can also affect scallop populations, and external factors like the price of scallops or gasoline can influence the intensity of fishing effort. So, changes in a fishery often lead to outcomes that don’t necessarily generate neat bullets you can compare on a balance sheet.

It’s especially challenging to plan for both short and long term changes in a fishery. Most fisheries are managed to accommodate short-term changes that last a few years, like natural fluctuations in population size. But fisheries management today generally doesn’t also consider long-term changes spanning many decades, like warming and ocean acidification, even though we know those changes are gradually tilting the playing field for many marine species.

Future Leaders Fight for Trash Free Seas

Posted On April 24, 2015 by

Each year Ocean Conservancy’s International Coastal Cleanup draws volunteers of all ages together to remove trash from the lakes, rivers and coastlines they love. As we approach the thirtieth Anniversary of this global trash-free-seas effort, and take a retrospective look at all the Cleanup has accomplished, we know that children and students continue to play a major role in its success.

In the past two years alone, over 151,000 youth across the globe have participated in an International Coastal Cleanup event.  For all volunteers, especially kids, a cleanup experience is also an educational one. Engaging the next generation on the impacts of ocean trash and, most importantly, how we all can prevent it is vital if we are to stop further flow of debris into the ocean.
