Amy is a stream ecologist who, before working at Ocean Conservancy, conducted research focusing on small stream food webs and the predator and prey dynamics of salamanders. Amy has conducted research in Chile working with the government on invasive beavers and water quality issues as well as nutrient effects on small streams in the southeastern U.S. She also spent several years working on Waters of the United States as part of the Clean Water Act. Her work at Ocean Conservancy currently focuses on ensuring ocean planning is a coordinated, science-based policy to balance all ocean uses.
Yesterday, President Trump signed an executive order that would start rolling back a rule under the Clean Water Act known as Waters of the United States (WOTUS). This rule enhances the health of our streams, rivers and ocean, supporting local communities and their desire for clean drinking water as well as fishable streams and estuaries. I have spent much of my life working on streams and water quality issues, I’m concerned this executive order will compromise local ecosystems and the clean drinking water Americans value and need.

After Hurricane Sandy hit the East Coast last October, I read an op-ed by Paul Greenberg in the New York Times titled “An Oyster in the Storm” that inspired me. In his piece, he described how oysters can be used to protect the shorelines of our coastal cities while improving the water quality of America’s largest metropolis. The solution to two major issues seemed suddenly so obvious. I needed to learn more.
So I partnered with a friend to produce a short documentary titled “Harbor Heroes” about the importance of oysters to New York City. We interviewed an amazing group of individuals including students from the aquaculture program at the New York Harbor School, Philippe Cousteau and Paul Greenberg himself.
How do oysters help water quality?
The idea behind restoring New York’s oysters is this: oysters grow on top of one another, forming nurseries for baby fish and creating a base structure for reefs. Reefs act as natural surge protectors and reduce the size of waves during big storms. Like other mollusks, oysters are filter-feeders, which means they clean the water column as they eat. If the water quality improves enough, sea grass could grow and create a root network that would prevent the erosion of the shoreline.

What does a healthy ocean look like? The Ocean Index brings together scientific data on everything from coral to the economics of coastal communities to answer this critical question. Credit: Arthur Koch
At Ocean Conservancy, we often get asked “How is the ocean doing?” That straightforward question is actually quite difficult to answer. This vast resource, our planet’s life support system, faces many complex challenges. Quantifying them is no easy matter.
The new Ocean Index announced in Nature is one way to assess and compare the health of ocean ecosystems across different countries. To date, there’s been no comprehensive source that brings together all manner of ocean-related research in one place. The Index is a good starting point.
Sixty-five scientists and other experts worked together to create this tool. They use a series of indicators to measure ten goals important to us all, including
The Index looks at the current status for each, as well as the likely scenario for sustainability into the future. Overall, the health of the ocean received a score of 60 out of 100. The United States is in the middle of the pack with a score of 63. Continue reading »
