- Humpback Whales' Dining Habits And Energy Costs Of Feasting On Tiny Prey, Revealed
As most American families sit down to Thanksgiving dinner, a University of British Columbia researcher is revealing how one of the largest animals on earth feasts on the smallest of prey -- and at what cost.
- Trouble In The Pipeline For Grey Whales
The fate of the world's few remaining western grey whales now rests on the outcome of appeals to Russian authorities and courts following the refusal of an oil consortium to consider alternatives to a proposal to lay an oil pipeline through a shallow lagoon crucial to the whales' food supplies.
- U.S. Navy Sonar Linked To Whale Strandings, Environmental Scientists Argue
With the U.S. Supreme Court due to review a series of lower court rulings that restrict the Navy's use of sonar in submarine detection training exercises off the coast of Southern California, George Mason University professor Chris Parsons discusses the links between mass strandings and military exercises worldwide in a paper in the Marine Pollution Bulletin.
- How Whales And Other Marine Mammals React To Sonar
Marine biologists have just completed a pioneering research effort in Hawaii to measure the biology and behavior of some of the most poorly understood whales on Earth. During the study, for the first time, scientists attached listening and movement sensors on marine mammals around realistic military operations.
- Whales And Dolphins Influence New Wind Turbine Design
By studying the flippers, fins and tails of whales and dolphins, scientists have discovered some features of their structure that contradict long-held engineering theories. These discoveries may have a strong impact on traditional industrial designs including wind turbines and helicopters.
- Whales Set To Chase Shrinking Feed Zones
Endangered migratory whales will be faced with shrinking crucial Antarctic foraging zones which will contain less food and will be further away, a new analysis of the impacts of climate change on Southern Ocean whales has found.
- Most North Pacific Humpback Whale Populations Rebounding
The number of humpback whales in the North Pacific Ocean has increased since international and federal protections were enacted in the 1960s and 70s, according to a new study conducted by more than 400 whale researchers throughout the Pacific region. However, some humpback populations still slow to recover.
- ScienceDaily: Sounds From the Sea -- Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive Aquatic Listeners, or PALs, at depths of up to hundreds of meters deep in oceans around the globe. PALs could also help track whales and other marine life.
- Endangered Right Whales Protected With New Warning Buoys In Shipping Lanes
Endangered North Atlantic right whales are safer along Massachusetts Bay's busy shipping lanes this spring, thanks to a new system of smart buoys. The buoys recognize whales' distinctive calls and route the information to a public Web site and a marine warning system, giving ships the chance to avoid deadly collisions.
- ScienceDaily: Gray Whales A Fraction Of Historic Levels, Genetic Research Says
While gray whales have recovered from the becoming nearly extinct in recent years, they haven't returned to their past abundance when whale hunting was common.
- ScienceDaily: Humpback Whales Recorded Clicking And Buzzing While Feeding For First Time
Researchers have now recorded feeding clicks made by humpback whales that are similar to those made by toothed whales. Previously, scientists had thought that only toothed whales made these clicking sounds, related to echolocation.
- ScienceDaily: Where Have All The Dolphins Gone This Summer?
Fewer dolphins seen this summer.
Researchers have seen nearly 80% fewer dolphins this summer in the Bay of Biscay. The decline could be a result of overfishing of the dolphins' main food source, the anchovies, and dolphin lost as bycatch in commercial fishing nets.
- ScienceDaily: Whale Has Super-sized Big Gulp
Baleen whales have a huge expandable mouth that can take in large amounts of water and food at one time, yet they eat the tiniest food, krill. Scientists have been studying these whales to find out how often they eat and just how much food they need. At the same time, they are also learning more about the feeding behaviors of these gentle giants.
- ScienceDaily: Whales In Hot Water: Global Warming's Effect On World's Largest Creatures
Warming temperatures will have a serious impact on the survival of whales, dolphins, and porpoises.
- Pacific whale decline 'a mystery'
Grey whales in the eastern Pacific appear to be in some trouble, with the cause far from clear, scientists say.
- ScienceDaily: Whales Entangled In Fishing Lines: What Can Be Done?
Lobster fishing in the Atlantic is affecting the highly endangered right whale as whales become entangled in fishing lines.
- Marine Scientists Monitor Longest Mammal Migration
Humpback whales' record-breaking migration of over 5000 miles has been recently recorded by scientists. Some humpbacks traveled from Antarctica as far north as Costa Rica. Researchers also confirmed the theory that humpback whales migrate to warmer waters during winter.
- ScienceDaily Video: Sounds From the Sea -- Acoustical Oceanographers Record Noises in the Deep
Sounds are different underwater than above water. To study the impact of underwater noise, scientists have placed listening devices to record underwater sounds.
- Daring hunt strives to free rare whale
Rescuers working from two boats in Onslow Bay on Wednesday adapted centuries-old hunting techniques to free a rare whale from a length of fishing line. Rescuers have been trying to free a rare right whale from a length of fishing line. They've been only partly successful, but the young whale can now eat.
- Saving Endangered Whales At No Cost
Making simple changes to current lobster fishing practices could result in a win-win situation for both fishermen and endangered right whales. Many of the remaining 350 right whales in the North Atlantic suffer from entanglement in lobster gear. Reducing the number of traps
and shortening the lobster season could result in a safer environment for these endangered whales.

The Arctic winter wonderland, known for its icy waterways and white snowy scenery, is experiencing record low sea ice in the last two years. Click the following to access the link:
- Entangled Humpback Whale Rescued in Hawaiian Waters
A team of ocean researchers and divers successfully rescued a humpback whale off the Hawaiian Islands. The whale had become entangled in fishing gear. Rescuers were able to successfully cut away the lines. For more information, go here:
