Finding minuscule life forms in a seemingly infinite ocean isn’t trivial. But in recent years, oceanographers have been developing new techniques and instruments to identify and count marine microorganisms. Year by year, we are learning more and more about them and discovering that they are even more numerous, varied, and important than we previously thought.
Light in the ocean is like light in no other place on Earth. It is a world that is visibly different from our familiar terrestrial world, and one that marine animals, plants, and microbes are adapted to in extraordinary ways. Light behaves very differently when it moves from air into water. It moves through the expansive depths of an ocean that is devoid of solid surfaces. These and other factors combine to create an environment that has no equivalent on land.
Capped with a formidable ice and snow cover, plunged into total darkness during the winter, buffeted by blizzard winds,and bitterly cold, the Arctic Ocean is one of the most inaccessible and yet beautiful environments on Earth. Life here endures some of the greatest extremes in light and temperature known to our planet. Yet despite these inhospitable conditions, the Arctic Ocean is teeming with life.
“We have found that otoliths of fish born in each of the five natal estuaries had different, unique isotope and element compositions, or “signatures.” All their lives, these fish had carried a natural tag, encoding the location where they were hatched.
In recent decades scientists have made substantial progress in understanding how oil enters the oceans, what happens to it, and how it affects marine organisms and ecosystems. This knowledge has led to regulations, practices, and decisions that have helped us reduce sources of pollution, prevent and respond to spills, clean up contaminated environments, wisely dredge harbors, and locate new petroleum handling facilities.

April 24 marks the first-ever Right Whale Day in Massachusetts. WHOI biologist and veterinarian Michael Moore recently met with the resident who brought this special recognition about– and explains why it’s important to raise awareness about the critically endangered North Atlantic right whale.
A report out this week in Current Biology reveal that critically endangered North Atlantic right whales are up to three feet shorter than 40 years ago. This startling conclusion reinforces what scientists have suspected: even when entanglements do not lead directly to the death of North Atlantic right whales, they can have lasting effects on the imperiled population that may now number less than 400 animals. Further, females that are entangled while nursing produce smaller calves.
