2016 Deepwater Exploration of the Marianas

Mission Introduction

By Kelley Elliott, Expedition Manager, NOAA Office of Ocean Exploration and Research
April 20 – July 10, 2016

From April 20 to July 10, a team of NOAA and external partners who are participating both at-sea and on shore will conduct the 2016 Deepwater Exploration of the Marianas expedition.

The 69-day expedition will include three cruise legs to conduct mapping and remotely operated vehicle (ROV) operations in the deep waters of the Marianas Trench Marine National Monument (MTMNM) and the Commonwealth of the Northern Mariana Islands (CNMI).

The primary expedition goal is to acquire baseline information in deepwater areas to support science and management needs in and around the Monument and other protected places. Operations will focus on understanding the diversity and distribution of deepwater habitats in and around the CNMI and MTMNM.

In the coming months, we expect to explore bottomfish habitats, new hydrothermal vent sites, mud volcanoes, deep-sea coral and sponge communities, seamounts, subduction zone areas, and trench areas. All of these exciting features are within the U.S. exclusive economic zone. ROV dives will include high-resolution visual surveys and limited collections of geological and biological sampling.

We never know exactly what we will find, so tune in to the live feeds to see what we discover next!

    The Bottom Fishery in the Mariana Islands

    The cultures of the indigenous inhabitants of Micronesia are characterized by an intimate relationship with the ocean. This seafaring bond is realized most strongly through fishing, an activity which has sustained Micronesian cultures for millennia.

    Hydrothermal Vents

    When most people think of the deep sea around the Commonwealth of the Northern Marianas Islands and the Marianas Trench Marine National Monument, they immediately think “the deepest part of the ocean.” And while the Marianas Trench is amazingly cool, there are other equally awesome habitats within the monument, such as hydrothermal vents.
