  • Why you want oysters and a salt marsh between you and a hurricane

    Instead of building hard seawalls to protect communities from hurricanes, some are turning to “living shorelines.” These are made out of crushed rock or oyster shells that are placed offshore in front of a wetland. There are more than 120 of these types of habitats — including in Beaufort, North Carolina — and they have shown that they can absorb 50 percent of wave energy, which can reduce the risk of loss of human life and property from flooding. This might not work for all coastal communities, but living shorelines are cheaper than the traditional seawalls.

  • Fish Below Your Feet and Other Solutions for a Living Harbor

    Around the world, scientists are eco-engineering urban waterfront areas to encourage marine species diversity. Seattle’s Central Waterfront area was recently enhanced with a textured and angled concrete sea wall to encourage the growth of algae and invertebrates, a built-up seafloor to attract juvenile salmon who like shallow water, and light penetrating glass bricks in the sidewalk, which boost seaweed growth and entice shade-avoidant salmon smolts. The project also enhances the human experience with more pedestrian access, better storm water management, and a new pier park with direct water access.

  • Coastal Recovery: Bringing a Damaged Wetland Back to Life

    A coastal recovery project in Delaware Bay is using a technique that they call "engineering with nature" to bring back the 4,000 acres of wetlands from the disastrous effects of human interference and climate change. They use a multitude of strategies, such as stabilizing the dunes and replanting native grasses, and although they approach the project as a research study without progress yet, they have already begun to see a return of wildlife including birds, eels, and crabs. Similar efforts to restore wetlands are also taking off across the globe.

  • pH7

    After the legacy of acid mine drainage from abandoned coal mines in Appalachian Ohio, there are several initiatives working to clean up the rivers and streams. Change-agents from universities, local organizations, and the government joined together in the 1990s to use both active and passive methods of neutralizing the pH level of the streams. Since then, they've brought the pH acidity down from 4.5 to 7 and grown the number of fish species from 4 to 37, and efforts are still ongoing and optimistic.

  • Technology in the tides

    A new submersible machine produced by the Mote Marine Laboratory in Florida allows scientists to more effectively spot phytoplankton blooms which can cause red tide. This harmful algal bloom event can wreak havoc on ecosystems and the Programmable Hyperspectral Seawater Scanner is an improvement on an older model. While the maintenance cost can be high, scientists hope the instrument will be able to detect harmful algal blooms early in order to prevent outbreaks.

  • Can Scientists, Entrepreneurs, And The Private Sector Come Together To Save Sharks?

    The research group, Beneath the Waves, is cultivating cross-sector collaborations with nonprofits, scientists, and individual philanthropists in order to better study the movements and patterns of sharks in the Bahamas. What has typically been a challenging task has been made possible through the use of acoustic tags, which can provide researchers insight into ocean ecosystems and thus conservation. Such initiatives are part of a larger trend of bringing together private donors, nonprofits, and ocean scientists to bolster marine science and conservation efforts.

  • Could Hawaii Be Paradise For Hydrogen-Powered Public Transit?

    Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

  • Scientists use mini-satellites in effort to save the world's coral reefs

    As coral reefs around the world are threatened by warming waters, mini-satellites are collecting images each day from space that put together a more comprehensive picture of the problems. This saves scientists time, energy, and money, and it means resources can be better targeted to the reefs that need the most help.

  • Going Dark to Reconnect to the Night Sky

    Light pollution threatens access to nature and its views of the stars, but it also negatively impacts health by disrupting sleep and human circadian rhythm. The International Dark-Sky Association has been working for years “to protect naturally dark sky,” educate others, and increase engagement with the stars.

  • Tribes Use Western and Indigenous Science to Prepare for Climate Change

    The University of Washington and Northwestern tribes have partnered to use their collective knowledge to create an online tool that helps regional tribes prepare for the effects of climate change. The tools uses climate forecasting that depicts how different resources in the region will be affected at a hyper-local level. The tool itself is a result of Western science, but researchers say the inputted data and information would not have been possible without the nuanced Indigenous knowledge.
