Tides and Waves: Sources of Endless Energy

Today’s guest post by Amin Mivehchi is a brief introduction on harnessing tidal energy from the power plants of the future: OCEANS! More than 70% of our planet is covered by bodies of water and it’s time to invest in harnessing this infinite source of renewable energy.

The Atlantic Ocean is the Culprit in the Case of the Cooling Eastern Pacific

A classic climate “Whodunit”? Can researchers get to the bottom of the mystery of the cooling eastern Pacific Ocean, three decades in the making?

Scaredy-crab behavior can alter food webs

Being small crab can be tough. Dodging predators from the land, sea, and air is no small task. A new study focuses on the convergence of individual behavior with ecosystem dynamics, showing how mangrove tree crab behavior may link distinct aquatic and terrestrial food webs.

Armored but uninhabited: how beach armoring is altering transitional communities

Let’s get back on the beach for the final day of spring break! Here we explore the unique communities inhabiting beaches and how human efforts to prevent erosion are hurting them.

It’s ALIVE: Living Shorelines!

It’s no secret we want to protect our shorelines from erosion and coastal storms. One best management practice catching steam is a living shoreline, which uses native vegetation instead of concrete. Living shorelines not only have the potential to protect coastal communities, but may also be a carbon sink.

Storm Troopers! Robots collect ocean data during hurricanes

Hurricane prediction models are constantly improving as we create more innovative ways to study the growth and development of storms. In 2011, a team from Rutgers University sent an autonomous underwater vehicle into the projected path of Hurricane Irene to measure ocean conditions before, during, and after it passed.

Ports, Pups, Policy, and Low Sardine Stocks

While sardine stocks are seeing disturbingly low numbers along the US west coast, affecting fishermen and marine mammals that depend on them, scientists are working hard to provide forecast modeling and data than can better assist fishery managers to avoid this situation in the future.

Summiting Sand Dune Crests: A challenge of restoration

With spring break upon us, we’re all looking for a way to unwind and have fun. For some areas relying on tourism for economic stability, though, fragile habitats can often be overlooked in an effort to keep money flowing in. Click here to find out more about new research being conducted on restoring one of Brazil’s vulnerable microbiomes: sand dunes.

Wake

Manipulating ship wakes to reflect light could help fight climate change

The tiny bubbles produced by ship’s wakes reflect light and cool the planet. Could they be manipulated to counteract global warming?

Of whales and cows: the baleen whale microbiome revealed

Scientists sequenced the microbiomes of several baleen whales that are strict carnivores and found some startling similarities to the microbiomes of terrestrial herbivores.

For Sea Turtles, There’s No Place Like Home

Tagline: Sea turtles are occasionally released in locations that are not their home areas. But do they remain there? Find out in today’s oceanbites!

Walrus whiskers

What’s up with Whiskers?

Whiskers are like finger tips for flipper-footed marine mammals, like seals, sea lions, and walruses. Learn more about how pinnipeds use their whiskers to track prey, and discriminate between different objects by size, shape, and surface structure.

Ocean robots record California’s latest hot year

Using underwater gliders, researchers explain what caused the extremely warm ocean along the coast of California in 2014-2015 and what this might mean for local ecosystems.

Arctic could become more biologically productive as ice melts

As Arctic sea-ice melts away, organisms will be exposed to more light and, potentially, more nutrients. Recent model work suggests that this combination will result in a more biologically active Arctic. But the net result might not be as positive as you think.

dinner bell

Are satellite tags the new dinner bell for harbor seals?

Satellite tags are being used to study the foraging behavior of fishes, but in the lab harbor seals have been found to be attracted to the acoustical signal given out by these tags. In the wild, does that mean these tags are acting as a dinner bell for harbor seals?
