This is the third in a series of ocean infographics by artist Don Foley. These infographics also appear in Oceana board member Ted Danson’s book, “Oceana: Our Endangered Oceans and What We Can Do to Save Them.”
Last year’s Deepwater Horizon blowout in the Gulf of Mexico was not an isolated event. The exploding rig was especially tragic, but the truth is that the oil industry produces pollution every day, as today’s infographic illustrates:
The small spills associated with oil extraction, transportation, and consumption add up to about 195 million gallons every year. That’s as much as one Deepwater Horizon gusher.
As we saw in the Gulf of Mexico in 2010, extracting oil from the seafloor is dangerous business. Everyday drilling and extracting result in chronic leaks that add up to 11 million gallons of oil pollution annually.
Transporting oil is also a major source of pollution. Sometimes ships intentionally discharge what’s known as oily ballast water—the thousands of gallons of dirty water used to keep a giant transport ship stable. Otherwise, despite their best attempts, moving oil around inevitably results in spills to the tune of 44 million gallons a year.

With shark week fast approaching, how about a shark-related infographic to whet your appetite?
Today’s infographic illustrates how overfishing fundamentally alters ocean ecosystems, leading to fewer and smaller fish over time.
If overfishing isn’t stopped, the largest fish like sharks, tuna, cod, and salmon eventually run out and overfishing expands to previously untargeted, smaller species, some of which were considered undesirable. As a result, the world catch is now primarily made up of small fish like pollock rather than large predators like grouper, and this shift to smaller and smaller species over time is called “fishing down the food chain.”
Since a lot of what happens in the oceans is hidden from view, the issues we discuss here on the blog can often be abstract and hard to visualize.
That’s why starting today, I’ll be featuring an ocean infographic by artist Don Foley each week. These infographics also appear in Oceana board member Ted Danson’s book, “Oceana: Our Endangered Oceans and What We Can Do to Save Them.”
I thought I’d start with one of the most mysterious players in the ocean: fishing gear. I don’t know about you, but I’ve never actually seen any of these in real life (have you?), so I find this infographic quite helpful:
Dredges catch scallops and fish by dragging across the seafloor. They can crush corals, catch sea turtles, and disturb all kinds of seafloor life.
Purse seine nets catch schooling fish like tuna by encircling the school with a wall of netting. They can capture dolphins and other natural predators feeding on the school.
Trawl nets catch shrimp, cod, haddock, and other fish. Bottom trawls drag weighted nets across the seafloor, crushing corals or any other marine life in their path. Bottom trawls also discard more unwanted fish than almost any other form of fishing and are extremely destructive. Midwater trawls drag large nets through the water to catch pollock and other schooling fish, and when their nets are full, they may also drag on the bottom.
Gillnets are one of the most widely used methods in the world for catching salmon and sharks. When not closely tended, gillnets can entangle and drown sea turtles, seabirds, and marine mammals. Some gillnets also snag large numbers of juvenile fish, which contributes to overfishing.
