Sea levels in the Chesapeake Bay region of Virginia are rising at a rate more than twice the global average. Since 1960, the area has experienced a 325 percent increase in “nuisance flooding” that disrupts business by closing roads and flooding parking lots and putting undue stress on infrastructure, like storm water drains, roads and sidewalks.
Some of this recurrent flooding is due to the land settling, the geologic results of a massive meteor strike here 35 million years ago. But there’s little doubt the Virginia coast is also on the frontline of climate change, surging waters and more intense storms. It’s no longer a question if and when the sea will rise here; the challenge is how much and how to adapt.
The Chesapeake Bay is our nation’s largest estuary and home to more than 3,600 species of plants and animals, including thousands of acres of valuable coastal marsh and wetlands. Scientists anticipate Virginia will lose 50-80 percent of these wetlands in the next 50 years at the current rate of sea-level rise. And it isn’t just the beautiful vistas we’ll lose, but everything else these wetlands provide—protection from erosion near waterfront property; flood control; filtration of runoff and removal of pollutants; and the food, water and habitat for the critters that call the wetlands home.
The busy Hampton Roads area is the second most populated region at risk from sea level and related storm damage after New Orleans. And it is home to the world’s largest Navy base. During a speech at the College of William and Mary, Sen. Tim Kaine (D-VA) remarked that in another 25 years, the main road into Naval Station Norfolk, will be under water three hours a day.
Thus, climate change not only threatens our way of life, but it’s threatening our national security as well. We need to mitigate its effects with short- and long-term strategies. We need to adapt to these changes by developing environmentally smart infrastructure that not only allows us to live in a rapidly changing world, but minimizes climate changing pollution for the future.
The Chesapeake Bay Foundation’s new Brock Environmental Center in Virginia Beach is designed to do just that by minimizing CO2 emissions, limiting environmental impacts and adapting to rising sea-levels. The center is built on pilings more than 14 feet above sea level and 200 feet back from the river’s edge (double the 100 feet clearance required by Virginia law), safe from both rising sea levels and storm surges.
The Brock Environmental Center also utilizes existing technology and common-sense design features to meet the Living Building Challenge, the highest standard for environmentally smart building. Two small wind turbines and roof top solar arrays generate enough energy to power the building. Geothermal wells, windows that open and close according to temperature needs, super-insulated walls and floors, and natural ventilation features—heat and cool the building.
And rain cisterns and a filtering system make the Brock Environmental Center the first project in the U.S. to receive a commercial permit for drinking filtered/treated rainwater in accordance with the federal drinking water requirements. In fact, the center uses rainwater for all its water needs.
The builders also extensively used recycled and salvaged materials to reduce waste, and they excluded more than 300 hundred toxic materials typically found in common building materials.
Finally, the building was designed to prevent site disturbance—there is no parking lot on site, and it is landscaped in native trees, shrubs, and grasses to restore years of displaced wetlands. The natural landscaping allows flood waters to rise, settle and recede naturally without harm to the center or nearby neighborhoods.
Now open for business, the Brock Environmental Center allows the Chesapeake Bay Foundation to continue its groundbreaking work saving the bay in Hampton Roads while providing a national model for smart building, energy efficiency and climate-change adaptability.

Human actions have taken a steep toll on whales and dolphins. Some studies estimate that small whale abundance, which includes dolphins, has fallen 87% since 1980 and thousands of whales die from rope entanglement annually. But humans also cause less obvious harm. Researchers have found changes in the stress levels, reproductive health and respiratory health of these animals, but this valuable data is extremely hard to collect.

A Lot to Learn From Hormones<p>When sampling the blow, we are looking for hormones in mucus as these can be used to gauge psychological and physiological health. We are specifically interested in <a href="https://dx.doi.org/10.1371%2Fjournal.pone.0114062" target="_blank">hormones like cortisol</a> and <a href="https://doi.org/10.1016/j.ygcen.2018.04.003" target="_blank">progesterone</a>, which indicate stress levels and reproductive ability respectively, but can also help determine overall health.</p><p>Additionally, blow samples can detect <a href="https://dx.doi.org/10.1128%2FmSystems.00119-17" target="_blank">respiratory pathogens</a> in the lungs or nasal passages - blowholes evolved from noses after all.</p><p>This health analysis is especially important in areas with oil spills as the chemicals can cause hormonal problems that harm <a href="https://www.carmmha.org/investigating-how-oil-spills-affect-dolphins-and-whales/" target="_blank">development, metabolism and reproduction</a> in dolphins.</p><p>Hormone samples can provide scientists with valuable data, but collecting them from intelligent and unpredictable animals is challenging.</p>
Cetacean Collaborators<p>To build a drone that can stealthily collect spray from moving dolphins, we needed more data on their eyesight and hearing, and this is data that couldn't be collected in the wild nor simulated in a lab.</p><p>We worked with dolphins at facilities like Dolphin Quest in Bermuda, which provides guests opportunities to learn about dolphins while allowing <a href="https://dolphinquest.com/about-us/our-story/" target="_blank">scientists access to animals for noninvasive research</a>. Here the dolphins can swim away if they choose not to work with us, so we had to design the study like a game; the way a kindergarten teacher entertains a class. If the dolphins aren't interested, we don't get to do the science.</p><p>Over the course of hundreds of sessions, we sought to answer two questions: What can dolphins hear and what can they see around their heads?</p><p>To test dolphin hearing, we set up microphones and cameras to record dolphin behavior as we played drone noise in the air. We analyzed the responses to each noise – such as how many dolphins looked at the speaker – and used these as a proxy for their ability to hear the sounds.</p>

Robodolphin doesn't look like a real dolphin, but it doesn't need to in order to train our drone pilots. C.J. Barton / Oklahoma State University / CC BY-ND<p>To build robodolphin, we worked with dolphins trained to "chuff" or sneeze on command to measure spray characteristics. We used high-speed photography to see the dolphins' breath as it moved through the air. Then we conducted high resolution CT scans of a dolphin head and 3D-printed a replica of a nasal passage.</p><p>Now, we have a complete robodolphin and are tweaking its sprays to be nearly identical to the real thing. This will allow us to determine how close we need to get to collect the samples, and therefore, how quiet our drone needs to be.</p>

A Bit of Practice, Then Into the Wild<p>In the next few months, we will test flights over robodolphin with existing drones to determine the timing and strategy for collection. From there, we will fabricate a low-noise drone that can fly fast enough and with sufficient maneuverability to capture samples from wild dolphins. Like a video game, we will use the visual field data to develop approach trajectories to stay in the visual blindspots.</p><p>We plan to test our drones on a truck-mounted robodolphin moving down a runway, then using a boat to simulate realistic conditions. The next steps will involve ocean testing with dolphins trained for open ocean swimming. These tests will determine if our devices can catch and hold the hormones as the drone flies back to a researcher's boat.</p><p>Finally, we will deploy the system to collect data on wild dolphins. Our first goal is to test resident dolphins – animals that live on the coasts and deal directly with boat and oil industry noise – which will allow us to learn more about stress resulting from human impacts.</p><p>Those samples are a way off, but if all goes well we will have a specially built drone capable of flying long distances and capturing samples undetected in a few years. The samples collected will allow researchers to do better science with impact on the animals they study.</p>

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>
