Life at the Edge

What makes the shelf break front such a productive and diverse part of the Northwest Atlantic Ocean? A group of scientists on the research vessel Neil Armstrong spent two weeks at sea in 2018 as part of a three-year, NSF-funded project to find out.

Illuminating the Ocean with Sound

Illuminating the Ocean with Sound

WHOI’s new research vessel Niel Armstrong is equipped with an EK80 broadband acoustic echo sounder. Using a wide range of sound frequencies, it gives scientists the ability to identify and distinguish between different types of marine life in the depths.

The Quest for the Moho

The Quest for the Moho

For more than a century, scientists have made several attempts to drill a hole through Earth’s ocean crust to an interior layer of rock in Earth’s interior called the mantle.

Remembering Knorr

After an iconic, 44-year career, the research vessel Knorr left the dock at Woods Hole Oceanographic Institution in March for the last time. It also left a place in the hearts of many who sailed on the ship or who had simply seen it in Woods Hole. A few of the people who watched it depart shared their memories of Knorr in this audio postcard.

Ready, Set, Dive

Before scientists go to work in the morning at the bottom of the ocean in the submersible Alvin, a team of engineers, pilots, and ship’s crew performs a carefully orchestrated choreography.

Replacing the Fleet

Replacing the Fleet

When R/V Atlantis arrived in Woods Hole for the first time on a bright, beautiful April 1997 day, it represented not only a welcome addition to the WHOI fleet but also the culmination of a 15-year UNOLS fleet modernization.

WHOI and Access to the Sea

WHOI and Access to the Sea

In the mid-term future, two WHOI ships (Knorr in about 2006 and Oceanus in about 2009) will reach the end of their planned service lives. There is general agreement that WHOI should work to replace them with two vessels.

A Northern Winter

A Northern Winter

As the 1996-1997 ship schedule began to take shape in 1995, we learned that Voyage 147 would take R/V Knorr into the North Atlantic from October ’96 through March of ’97. The various science missions would require station keeping during CTD casts, deployment of current drifters, and expendable bathythermograph (XBT) launches, as well as weather system analysis designed to put Knorr in the path of the harshest weather conditions possible during the winter season. Long before the cruise, we began to tap all available assets that would help us with this challenge.

Access to the Sea

Access to the Sea

Oceanographic fieldwork has traditionally meant going to sea on a ship. In recent years, it has expanded to include activities that may require a ship for a short period but then continue independently. Floats that drift with ocean currents, periodically reporting their positions via satellite, for example, are generally launched from ships but do most of their work independently. Long-term seafloor observatories may need ships to set them up and service them occasionally, but, again, they are designed to collect data for long periods without needing a ship. We have come to think of the body of ways oceanographers glean information from the ocean as “access to the sea,” and so that is the topic for this issue of Oceanus.

Alpha, Bravo, Charlie…

Alpha, Bravo, Charlie...

The ocean weather station idea originated in the early days of radio communications and trans-oceanic aviation. As early as 1921, the Director of the French Meteorological Service proposed establishing a stationary weather observing ship in the North Atlantic to benefit merchant shipping and the anticipated inauguration of trans-Atlantic air service. Up to then, temporary stations had been set up for special purposes such as the US Navy NC-4 trans-Atlantic flight in 1919 and the ill-fated Amelia Earhart Pacific flight in 1937.
