6Julia Cortez / AP PhotoDEICDear CBL Community,Today, August 26th, is Women’s Equality Day. It was originally designated in 1973 by the United States Congress to recognize the Women’s Surage Movement and the enactment of the Nineteenth Amendment in 1920, which prohibits denying the right to vote on the basis of sex. This day also draws attention to continued eorts in the U.S. to eliminate sex- and gender-based discrimination.On this day, it is also important to recognize that the Nineteenth Amendment did not grant the right to vote to all women, and that the Women’s Surage Movement, in many instances, was exclusive of women of color and immigrants. On Women’s Equity Day, we also celebrate the eorts of Black women to secure surage with the passage of the Voting Rights Act of 1965, which expanded voting rights to all women by outlawing discriminatory voting practices on account of race or color. Sincerely,The CBL Diversity Equity and Inclusion Committee (DEIC)The CBL DEIC is committed to listening, learning, and centering our community. Though we do our best to research all issues and content, we may not get everything right.

Tailwinds6General Tailwinds Updates* In July, FRA Caroline Tribble and PI Dave Secor attended the NY-SERDA State of the Science Workshop on Oshore Wind (OSW) Energy, Wildlife, and Fisheries at Stony Brook University. * Both presented posters highlighting research within the Tailwinds Fisheries Resource Monitoring and Marine Mammal Monitoring projects. The biennial meeting has grown to be the largest of its kind on oshore wind energy impact science for wildlife (marine mammals, birds, and even bats!) and sheries.Marine Mammal Monitoring* Flashing back to the beginning of summer, UMCES team members Caroline Tribble and Mike O’Brien along with Cornell University personnel Fred Channell and Derek Jaskula were back oshore to retrieve and re-deploy monitoring devices from our passive acoustic monitoring array. The devices recovered were deployed in October 2023 and monitored for the presence of large baleen whales, dolphins, porpoises, and sh with acous-tic tags. Shown in the picture, captain Evan Falgowski (far left) from University of Delaware and Tailwinds eld team members Fred Channell, Derek Jaskula, and Mike O’Brien (far right) aboard the R/V Daiber prior to device recovery.* During the recovery operation the team observed a diverse range of biofouling on the instruments, including mussels, sea stars, spider crabs, and even a sea urchin! Check out some of the interesting invertebrates that were found taking up residence on the equipment below.Photo credit: Dave SecorPhoto credit: Caroline TribblePhoto credit: Caroline TribblePhoto credit: Caroline Tribble Photo credit: Caroline Tribble

Box 38 | 146 Williams Street | Solomons, MD 20688-0038Safety Corner: Cheryl Clark8This is an account of a laboratory accident that I received from the Laboratory Safety Institute and I thought I would share it in the newsletter. There is a video of the individual involved in the accident at the bottom of the page. Please be sure to listen to her story. Three In OneWhile working in the lab, a researcher noticed someone had tried to introduce thionyl chloride into a reaction ask. However, instead of reaching the ask, the thionyl chloride had accidentally ended up in the vacuum trap, where it froze along with some solvent. Unaware of the dangerous substance in the trap, the researcher proceeded to pour the contents into a waste bottle. This routine task quickly turned hazardous, as thionyl chloride is highly reactive with water. The chemical mixture spewed out of the funnel, splashing onto the researcher’s face and torso. The situation escalated when the researcher, startled by the unexpected reaction, gasped—allowing the harmful chemical to enter their mouth. Immediately, they felt intense burning in their mouth and throat, and their vision became severely impaired. Despite the sudden panic, the researcher instinctively made their way to the eyewash station. With eyes closed, they managed to start rinsing the chemical o but quickly realized that their throat was burning too badly to call for help. In an attempt to alert a nearby colleague (because you should never work alone in the lab), the researcher began stomping and banging on the bench, hoping to draw attention. However, their eorts were initially unsuccessful because the other person was listening to music at full blast with head-phones on, drowning out any noise. Desperate, the researcher resorted to throwing magnetic stir bars in the colleague’s direction. Fortunately, one of the stir bars hit the colleague, catching their attention, and prompting them to come to this researcher’s aid. Take-Aways: Understand the Chemicals You Are Working With: Always be fully aware of the substances in your work area and their potential hazards. Thionyl chloride is known for its reactivity with water, making it particularly dangerous if mishandled.Never Work Alone: It is equally important that colleagues remain alert and aware of their surround-ings.Use Protective Gear and Follow Protocols: Proper use of personal protective equipment (PPE) and adherence to lab protocols can mitigate the risks of accidents.Be Prepared for Emergencies: Knowing emergency procedures, like where safe-ty equipment is located and how to contact help quickly, can make a signicant dierence in the event of an accident.Use of Headphones: Only use one earbud so that you can still be aware of your surroundings.Safety Goggles/Glasses vs. Vented Cover Goggles: Wear indirectly vented cov-er goggles, not directly vented safety goggles/glasses when working with hazard-ous chemicals. This researcher was wearing safety glasses at the time of the inci-dent. Therefore, when the reactant dripped down from her forehead it also dripped into her eyes, causing her impaired vision.
