Seeking Space Rocks

On March 7, 2018 at 8:05 PM local time, a meteorite broke up over the coast of Washington state, raining extraterrestrial rocks down into the ocean. This meteorite fall was detected by weather radars from the nationwide NEXRAD radar network, which recorded images of the falling rocks and data showing that they were composed of an unusually tough meteorite of unknown composition. … Continued

Deep Coral Diversity at Emperor Seamount Chain 2019

This expedition will feature exploration of the Emperor Seamount Chain while researching biodiversity and its drivers. Using currents, mapping, and radio isotopes to track water masses – as well as genetic sampling of corals – the team will determine the driving force behind coral distribution in this region.

Microbial Mysteries: Linking Microbial Communities and Environmental Drivers

The Gulf of California is a young ocean undergoing changes including active seafloor spreading, early rifting, and large-scale hydrothermal activity. The rare combination of geological dynamics present in the Gulf of California makes it an ideal place to advance our understanding of deep ocean hydrothermal ecosystems. The basin offers a natural laboratory for investigating changes … Continued

New Approaches To Autonomous Exploration At The Costa Rican Shelf Break

When NASA conducts planetary expeditions, they operate the vehicles through remote control - a person on Earth sends commands to the vehicle in space. However, even when using communications operating at the speed of light, there is a long gap in time between the transmission of the comand and the robot's reception of it. This … Continued

Costa Rican Deep Sea Connections

The deep sea is home to a variety of understudied, otherworldly ecosystems that are in need of human understanding if they are to have any protection from encroaching deep sea fishing and mining activities. These systems support the global marine environment through habitat creation, nutrient cycling, and maintenance of biodiversity. However, they also happen to … Continued

Interdisciplinary Investigation of a New Hydrothermal Vent Field

Scientists are always interested where hydrothermal vents are located. However, when a new field is discovered with properties not previously seen, the excitement reaches a whole new level. This occurred during a 2015 Monterey Bay Aquarium Research Institute (MBARI) expedition in the Gulf of California, when the science team found a unique and distinctive hydrothermal … Continued

Characterizing Venting and Seepage Along the California Coast

Hydrothermal vent and hydrocarbon seeps have been an important subject of oceanographic research over the last 35 years. Nevertheless, there are still many long-standing questions about these dynamic ecosystems, including their distribution and abundance in our ocean. Notably, the habitats are so unique that they mimic what environments might be like on other planets; this … Continued

Hunting Bubbles: Understanding Plumes of Seafloor Methane

While methane may not be the best known greenhouse gas, it nevertheless greatly impacts the climate system of our planet. Seafloor methane emissions have been documented for several decades, with newer evidence suggesting that methane bubble plumes from the deep sea are far more numerous than previously assumed. However, the physical, chemical and biological processes … Continued

Adaptive Robotics at Barkley Canyon and Hydrate Ridge

Conducting research with multiple underwater vehicles takes a huge amount of deliberation and coordination that is based on data gathered well before the work even takes place. But what happens if the environment you work on is constantly changing? Then the information you are basing your research on isn’t up to date. Additionally, there is … Continued

Sea to Space Particle Investigation

The Mariana region is home to the Mariana subduction system. This November, scientists shed light on the Mariana back-arc spreading center looking for new sites of hydrothermal activity.
