Back to Sea, Back to Work Although we crossed into a different time zone today (we are now in Mountain Time), the Western Flyer has no need to change its clocks an hour ahead. We will be on the boat for the next week so really, it matters very little what the time is elsewhere and it …

Time to refuel After just one day in port, the scientists were ready to get moving and back to science. Therefore, no one was too pleased when our fuel truck was delayed, pushing our departure back. The fueling process itself takes about two hours as 75,000 liters of fuel are pumped into the ship. Once …

Aquí estamos en México We arrived in Ensenada early this morning and began the process of clearing the R/V Western Flyer through Mexican customs. The process went smoothly and Francisco Chavez was able to make it off the boat in time for his talk at El Caracol—the soon-to-be maritime museum of Ensenada where he spoke about the Gulf …

Passing the time in transit Today was an unusual day for the scientists aboard the Western Flyer—we made no new casts and spent the entire day in transit. Travelling at about 10 nautical miles per hour since leaving M1 yesterday, we are now off the coast of San Diego. We are making good time even with …

First day of the expedition Like many of you reading this cruise log, I am not a scientist and I’ve never been on a research expedition before. Needless to say, boarding the Western Flyer—an MBARI research vessel named for the sardine boat that John Steinbeck and Ed Ricketts took to the Sea of Cortez in 1940—this …

In early January 2015, a team of MBARI engineers, led by Andy Hamilton, set out to sea to recover an experimental buoy that creates electrical energy from ocean waves. This power buoy had been deployed six miles southwest of Moss Landing Harbor for 131 days, while engineers tested the system’s ability to handle storms.

Dec 10, 2014 – MBARI Senior Research Technician Shannon Johnson Williams described five new species of Alviniconcha snails using DNA sequences. These snails live in the hottest and most acidic waters near hydrothermal vents. Because they live in these extreme conditions, Alviniconcha snails have severely degraded shells covered in spikes or they have no shells at all.

In the deep waters of the ocean, there are no places to hide. To avoid predators, many deep-sea animals have dark-colored, reflective, or transparent bodies. Others have evolved elaborate methods of deception.

On Monday, November 17, MBARI Senior Scientist Bruce Robison was leading a dive using the remotely operated vehicle Doc Ricketts in Monterey Bay when he came across this amazing deep-sea anglerfish about 580 meters (1,900 feet) below the ocean surface.

Over one thousand miles wide and three thousand miles long, the Sargasso Sea occupies almost two thirds of the North Atlantic Ocean. Within the sea, circling ocean currents accumulate mats of Sargassum seaweed that shelter a surprising variety of fishes, snails, crabs, and other small animals.

Sept 15, 2014 – Ocean researchers are on the verge of gaining new insights about the changing Southern Ocean with help from sensors developed by a research team at the Monterey Bay Aquarium Research Institute (MBARI).

Researchers at the Monterey Bay Aquarium Research Institute (MBARI) have observed a deep-sea octopus brooding its eggs for four and one half years—longer than any other known animal.

Cephalopods—squids, octopuses, and their relatives—are some of the most beautiful and intriguing animals in the ocean. During the week of June 23-27, 2014, MBARI, the Monterey Bay Aquarium, and Science Friday teamed up to present a wonderful array of videos and still images of these creatures.

From the vampire squid to the flapjack octopus, deep-sea cephalopods come in an amazing variety of shapes and sizes. Yet few humans have seen these animals alive. Since April, members of the public have been able to see these animals for the first time, as part of the ongoing Tentacles special exhibition at the Monterey Bay Aquarium.

Thousands of shipping containers are lost from cargo vessels each year. Many of these containers eventually sink to the deep seafloor. In 2004, scientists at MBARI discovered a lost shipping container almost 1,300 meters (4,200 feet) below the surface of the Monterey Bay National Marine Sanctuary.

Killer sponges sound like creatures from a B-grade horror movie. In fact, they thrive in the lightless depths of the deep sea. Scientists first discovered that some sponges are carnivorous about 20 years ago. Since then only seven carnivorous species have been found in all of the northeastern Pacific.

Since World War II, US nautical charts have shown seven “chemical munitions dumping areas” along the Pacific Coast between San Francisco and the Mexican border. However, little or no information is available about the amount, location, or nature of the materials that were dumped at most of these sites.

About 65 million years ago, an asteroid or comet crashed into a shallow sea near what is now the Yucatán Peninsula of Mexico. The resulting firestorm and global dust cloud caused the extinction of many land plants and large animals, including most of the dinosaurs.

Population booms of algae or animals near the sea surface can sometimes result in huge pulses of organic material sinking to the deep seafloor.

Many deep-sea animals such as anglerfish use parts of their body as lures to attract prey. Some deep-sea squids may use this strategy as well. In a recent paper, researchers associated with MBARI describe a deep-sea squid that appears to use a different method to lure prey—its tentacle tips flap and flutter as if swimming on their own.
