Over the months ahead we will learn about new approaches to solving the problems that will continue to be front and center for the ocean. If you need a refresher on the science we suggest you take a look at our overview pages: Climate Change Ocean Acidification Sea Level Rise But the elections also brought some local results that have immediate benefits for the ocean. For example: California Supports Plastic...Read more

Watt/Ocean Stock It’s hard to keep up with the latest news on the Internet. We all have information and headlines constantly streaming at us via Facebook, Twitter, email and news sites. We realize the Ocean Portal is a part of that noise. But since we are attempting to stay up-to-date on everything ocean, we thought, why not let you know what we are reading? Here’s our inaugural post. We will plan to give you an idea of what is going on in the ocean-world every two...Read more
Greenland Shark in cold water

In the Eyes of One Shark, Age is Nothing to Fear

Greenland Shark in icy Arctic waters. Credit: Julius Nielson In the freezing waters of the Arctic a toothed leviathan – the Greenland shark - claims an impressive feat. It now holds the record for longest documented lifespan of any vertebrate. The new discovery points to an age of roughly 400 years, meaning that some sharks swimming in today’s Arctic ocean may have shared the waters with explorers like Henry Hudson as he searched for the elusive Northwest Passage in the early 1600s. Little is known about Greenland sharks, and even shark specialists see them as creatures of mystery . Perhaps...Read more

In the Arctic, the Times, They Are a-Changin: You Can Pitch in to Understand How

This 1874 illustration of California gray whales ( Eschrichtius robustus ) shows a group of individuals at the edge of their modern day range in the North Pacific Ocean, blocked from traveling further east into Arctic waters by thick ice barriers. Credit: Plate V from Scammon 1874 ‘California grays among the ice’ Invasive species are often in the news these days, with human-transported organisms popping up in unexpected places. But in this era of climate change, there is a whole new kind of invasive species, those that are taking advantage of changing conditions to expand into areas not...Read more

Why the Littlest Fish Matter a Whole Lot

Recently starving sea lions have showed up on California beaches and are clamoring for fish at the mouth of Oregon's Columbia River ; tens of thousands of dead Cassin’s Auklets have washed up on shores from Alaska to California. Although we cannot say precisely why these animals are having such a hard time finding food, we can point to a problem with their food source, forage fish. What exactly are forage fish...Read more

Have We Hit The Chicken Little Point In Ocean Conservation?

Credit: Illustration from "Chicken Little" in the New Barnes Reader vol.1, New York, 1916 The sky is falling! The sky is falling! So cries Chicken Little (or Chicken Licken, or Henny Penny, depending on the telling) in the well-known folk tale . In the story, an acorn falls on Chicken Little’s head, and she takes it as a sign that the sky is falling and the world is coming to an end. She spreads the news—“The sky is falling! The sky is falling!”—and causes mass hysteria. In some versions of the story, her prophecy leads to her own demise: in a panicked state, she and her friends are easily...Read more

From Despair to Repair: Protecting Parrotfish Can Help Bring Back Caribbean Coral Reefs

Sit down with two veteran marine scientists, Dr. Nancy Knowlton and Dr. Jeremy Jackson, who fell in love with each other and the reefs of the Caribbean 40 years ago. Those reefs are now gone due to overfishing, pollution and overpopulation. But is there hope for reversing the trend? Reef biologists over a certain age are haunted by memories of what glorious places Caribbean reefs once were. In our youth we studied them for all sorts of reasons but scarcely thought about reef conservation. We took the reefs for granted. Today, however, we know that most Caribbean coral reefs will disappear in...Read more

The Great Barrier Reef – Going, Going, Gone???

Video of Storms, Starfish Wiped out Half of Great Barrier Reef Coral Dr. Nancy Knowlton, Sant Chair of Marine Science and Editor-in-Chief of the Ocean Portal, went on PBS NewsHour to talk about Great Barrier Reef and its massive coral loss . Australia’s Great Barrier Reef (or the GBR as it is known to reef aficionados) stretches for more than 2,300 kilometers (over 1,429 miles) and can be seen from outer space. This largest barrier reef in the world is both a national icon and a global treasure that was recognized as a World Heritage site over thirty years ago. Yet a recent study published in...Read more
