Oceans

Ocean Crab

In the 19th century humans knew little about the oceans, but other forms of life knew a lot. Our job over the last two centuries has been to catch up and surpass other forms of life in knowledge of the oceans. The advance of observation through science and technology, including new carriers and processors of information, has vastly expanded the oceans knowable to humans beyond what a sailor’s five senses could directly provide. By infiltrating the ocean with informationally connected sensors, humans are becoming the top experts on the oceans in the 21st century.

PHE has actively engaged in advancing oceanographic research of all kinds.  PHE director Jesse Ausubel conceived and managed The Census of Marine Life (CoML), a decade long (2000-2010) international research effort supported by the Alfred P. Sloan Foundation.  CoML aimed to document and assess the diversity (how many different kinds), distribution (where they live), and abundance (how many) of marine life—a task never before attempted at the global scale engaging some 2,700 scientists from around the globe. 

Currently active PHE Ocean research efforts focus on three areas:

Aquatic environmental DNA (eDNA). Analyzing “naked DNA” in water samples can reveal what animals are nearby. Aquatic eDNA offers low-cost, minimally invasive technology to complement traditional surveys, including in difficult environments, for protected species, and if pandemics or other events curtail routine surveys. We have tested this emerging technology in more than 700 samples from marine and freshwater environments, many from waters around New York City as well as diverse coastal habitats from Massachusetts to New Jersey.

With support from the National Oceanic and Atmospheric Administration (NOAA), our current efforts aim to improve accessibility, affordability, and reliability of core methods in marine eDNA metabarcoding. Working with NOAA, PHE is active in developing methods for Aquatic eDNA collection and analysis to further enable the use of this low-cost, minimally invasive technology to complement traditional surveys, including in difficult environments, for protected species, and if pandemics or other events curtail routine surveys.

Ocean Exploration. PHE hosted the 2016 National Ocean Exploration Forum at The Rockefeller University.  The meeting brought together a range of stakeholders to help identify and harness new technologies for ocean exploration including the growing role of autonomous vehicles. The Final Report of the 2016 National Ocean Exploration Forum (NOEF) found on the NOEF website, also includes reports from subgroups developing plans for exploration to the Arctic, the Gulf of Mexico, and the Southeast US Atlantic Bight.  The report contains PHE director Jesse Ausubel’s keynote address to the Forum: SuBastian and the Roboats 

International Quiet Ocean Experiment. The IQOE aims to complete a large-scale international effort to measure soundscapes of the world’s oceans and better understand potential biological effects of sound under the ocean surface.  Advances in signal processing are opening exciting new opportunities for passive acoustics to listen, for example, to coral reefs or kelp forests and learn about the diversity and abundance of species present.

Starting in 2020, the global COVID-19 pandemic created a sudden, dramatic reduction in the noise generated by international shipping offering an experimental control that has been the dream of IQOE scientists. In 2019, the IQOE began expanding its hydrophonic network used for ocean sound measurement and in 2020-2021 used the expanded network to measure ocean sound beginning with the first few months of the pandemic.  See Studying Marine Life’s Brief Break from Human Noise. High-quality observations of the ocean soundscape, as well as possibly related behavior of marine life during this period, may offer unique opportunities of exceptional value.

Integrating our streams of ocean research, we participate in the Clean Oceans International Working Group for the UN Decade of Ocean Science for Sustainable Development and in US efforts to lift benefits and lessen harms of the “Blue Economy.”
