CHESAPEAKE BIOLOGICAL LABORATORY | SOLOMONS, MDMARCH 2023ISSUE 79Lab Lines1IN THIS ISSUE:DIRECTOR’S VIEW23Based on a question at the last town hall meeting, I have arranged for a series of Wednesday seminars to take us to the end of the semester. Seminars, unless announced otherwise, will be at 11 am in BFL 1101 on Wednesday. Seminars have been added to the CBL calendar as titles are conrmed. The rst two are SAFETY CORNER IN CASE YOU MISSED IT/ PUBLICATIONS41Carys MitchelmoreMarch 29th, 2023 Environmental impacts of UV Filters: assessing risksThere has been a substantial amount of controversy recently over the impacts of UV lters, the active ingredients in sunscreens, on the aquatic environment. Concerns on impacts on corals have led to legislative action in several regions. But the scientic evidence for these impacts is limited and uncertain. Carys will provide an explanation of the state of the science, the key sources of uncertainty and how science and policy can become uncoupled.Dave Secor April 5th, 2023 UMCES Tailwinds: Assessing Impacts for Living Resources from oshore windUS Winds, Inc., is pursuing MarWin and Momentum wind energy projects in waters oshore of Ocean City, MD. In tandem with this development, UMCES TailWinds https://tailwinds.umces.edu/ is conducting a coordinated program of shery resource and marine mammal monitoring. The program follows BACI design principles and includes monitoring of (1) commercial and recreational shery resources, with a focus on black sea bass; (2) marine mammals (cetaceans: whales, dolphins and porpoises), using a passive acoustic monitoring array and emphasizing large whales, dolphins, and electronically-tagged shes; and (3) near real-time detections of baleen whales. In this talk, I introduce the MarWin and Momentum projects in the context of US oshore wind development, the TailWinds monitoring plan, and trial year ndings from 2022 deployments. Look for details about opportunities to meet other scientic and policy leaders coming to CBL this spring. I hope you will join us in BFL for interesting science and lively discussions.

In Case You Missed It2On Wednesday March 29 Vic Kennedy will be the Plenary Speaker at the 115th Annual Meeting of the National Shellsheries Association in Baltimore.Jackie Grebmeier spoke before the Arctic Circle Japan Forum on March 4. She also presented at the Seventh International Symposium on Arctic Research at the National Institute of Polar Re-search in Tokyo March 6-10. In addition, she presented a lecture on ecosystem adjustments by Zoom for the MEES Global Climate Change course from Tokyo.The NSF Eddie Bernice Johnson INCLUDES program supports the SEAS Islands Alliance, an eort to create culturally responsive workforce pathways for islanders from Puerto Rico, the U.S. Virgin Islands, and Guam. UMCES is a part of the SEAS Islands Alliance, in particular around the Puer-to Rico Hub. This month, NSF is organizing its second site visit review of our program. Because of the distributed nature of our Alliance, this is a "Reverse" site visit, where we interact virtually with a panel of external reviewers and NSF program ocers. In addition to providing NSF with our progress around broadening participation in the geosciences, the Reverse Site Visit oers an opportunity to reect on this work. It also means you may see Lora Harris looking a little more stressed than usual!

In Case You Missed ItIn early March, a team of four CBL scientists (Ryan Woodland, Theresa Murphy, Cindy Ross, & Lora Harris) traveled to the Virginia Institute of Marine Science for a meeting of our NSF supported project nicknamed "CHALK" (Chesapeake Alkalinity). The CHALK team is led by Ray Najjar at Penn State and also includes scientists from the USGS, WHOI, VIMS, St. Mary's College, and CBL. Our work focuses on understanding the macrobiotic controls (bivalves, SAV, wetlands) of alka-linity in estuaries that we highlighted as a potential mechanism for coastal alkalinity sinks and sources in a 2020 publication. This spring we are jump-starting a series of cruises on the Potomac and York River Estuaries that also extends to laboratory eco-physiology experiments, modeling, and historical data analyses.3PublicationsDib, V., Brancalion, P.H., Chou, S.C., Cooper, M., Ellison, D., Farjalla, V.F., Filoso, S., Meli, P., Pires, A.P., Rodriguez, D.A. and Iribarrem, A.,( 2023).

Safety Corner: Eye Safety4Since March is Workplace Eye Wellness month, this month’s tip is eye protection in the laboratory. According to National Institute for Occupational Safety and Health, there are more than 2000 eye injuries in the workplace every day.( https://www.cdc.gov/niosh/topics/eye/default.html) It is believed that 90% of these could have been avoided. Many of these injuries were due to the fact that individuals were not wearing eye protection or were not using the right kind of eye protection. Our eyes are our window to the world and the loss or impairment of one or both of our eyes would decrease our quality of life. Therefore, it should be common sense to take measures to protect them from harm, but we do not always do this. While most of us are quick to put our sunglasses on when we go outside to protect ourselves from the sun, we are not so quick about wearing eye protection in the labora-tory. We need to develop the habit of putting on the appropriate eye protection in the lab, just as we have devel-oped the habit of putting on sunglasses when we go outside. It needs to become second nature. The American National Standards Institute’s standard for occupational and educational eye and face protection is ANSI Z87.1. It has been adopted by OSHA and been made part of the federal requirements, making it the em-ployers responsibility to provide the appropriate protection equipment for workplace hazards. It is important to wear the correct eye protection. Be sure to check the labels and/or Safety Data Sheets (Section 8) of the chemical you are using. (It is also important that all chemicals be stored below eye level). If you are engaging in an activity where there is chance of an impact injury, be sure you have the correct safety glasses. Eye protection which com-plies with the standard are labelled ANSI Z87.1 or just Z87.1.There are three categories of eye protection – glasses, goggles and face shields. Safety glasses are used mostly to protect from impact. Your prescription glasses are not a substitute for safety glasses. Goggles are used for chemical protection and should t snugly around the eyes, so no dust or chemical can get through. There are two kinds, vented and indirect vented. If you are dealing with large quantities of chemicals, you should be using indirect vented. These have s-shaped vents so liquid cannot leak inside. The vented goggles are the type you see mostly in high school and undergraduate laboratories. These are more for impact and small quantities of chemi-cals and are not very eective to protect your eyes from a splash. Chemicals can get through the openings in the sides. Face shields are used to protect the face and throat from impact injuries. They will not protect you from chemical splash and should be worn in conjunction with safety glasses or gogglesOSHA now allows for contact lenses in the laboratory as long as you are wearing safety glasses or goggles. I per-sonally do not recommend it. There is the risk for chemical vapors to get behind the lenses and irritate the eye. Know where your eyewash station is located. Don’t wait for an injury to occur to nd it. If you get something in your eye, get to the station and ush eyes for 15 minutes. Have someone call 911 for you, if necessary.
