While this may seem unnerving, as CBL’s Interim Director, I look forward to working with you during our progression into this next phase. I am extremely condent in CBL's future as we connue to be a global leader in scienc research, transforma-ve educaon, and scienc service to the State and Naon. Just this month we have reasons to celebrate. Dr. Dave Secor received the Oscar E. See Award, by the American Fisheries Society, for his outstanding achievements in marine sheries. Dr. Hali Kilbourne was awarded the Wilson H. Elkins Profes-sorship from the University System of Maryland. Our sciensts connue to be called upon to provide expert data and advice to legislators, educators, and the general public. For more examples, check out the news secon and Jamie Testa’s arcles on Chesapeake Bay Dolphins.Looking ahead we have a lot going on. Our students are back to giving in-per-son talks at Naonal Scienc meengs. Samara Nehemiah, a Ph.D. student with Dr. Mike Wilberg, will be presenng her research and co-chairing a two-day symposium at the upcoming American Fisheries Society meeng. Dr. Lau-ra Lapham (Chief Scienst) and her team are heading out on the R/V Atlans to deploy the Alvin submersible to depths of 900m to study methane seeps. Our community has faced, and connues to overcome, many challenges. I am excited that we will connue our tradion of community engagement this Fall with our Science for Community lecture series and our Open House on Satur-day October 7th. This is the rst open house since 2019 and it is our chance to highlight to the community what we do and why it is important. Its success depends on you all, so please consider volunteering for this event. Stay tuned for more on these announcements in the upcoming weeks. Please remem-ber my door is open, stop by for a chat, the coee is on, and the chocolate biscuits plenful. As I wrap up this month’s newsleer I would like to give a huge shout out and thank you to Dr. Tom Miller. Your leadership and dedicaon to CBL over the past twelve years as our Director is evident throughout the campus and com-munity. CBL is truly a beauful and posive place to work and your enthusi-asm to the educaon, professional development, and career advancement of all CBL employees has been unwavering. Dr. Tom Miller’s summary of the recent Mid-Atlanc Fisheries Management Council’s meeng in this newslet-ter speaks exactly to this.Looking Ahead!

In Case You Missed It2Drs Ed Houde, Thomas Miller, Dave Secor and Mike Wilberg parcipated in the Mid-Atlanc Fisheries Management Council's Scienc and Stascal Commiee (SSC) meeng in Philadelphia, PA from July 24-26. During the meeng the SSC established maximum annual catch levels for bluesh, black sea bass, Atlanc mackerel and longn squid. Also parcipang as members of the SSC at the meeng were former CBL faculty member Brian Rothschild, former CBL post-doc Alexei Sharov and ex-students Mike Frisk (PhD, Miller) and Olaf Jensen (MS, Miller). Altogether, of the 20 members of the SSC, 8 (40%) have direct es to CBL. Moreover, the SSC is supported by senior MAFMC staer, Brandon Muey (MS, Houde), and heard presentaons from NEFSC assessment scienst Kiersten Cur (MS, Mill-er). Together this indicates the central importance of CBL's shery group in management of federal sheries in the region. Dr. Hali Kilbourne has been awarded an Elkins Professorship for Academic Transformaon for the 2023-2024 aca-demic year. This honor is awarded compevely to a faculty member in the University System of Maryland (USM) to support a project that can foster or illuminate improvements in access, quality of outcomes, and/or stewardship of people’s me, money, and other scarce resources. Dr. Kilbourne will be leading eorts to implement and improve learning outcomes assessment in the USM system-wide Marine Estuarine and Environmental Science graduate program.In January 2023 Carys Mitchelmore was part of the organizing commiee and a moderator for a Naonal Acade-mies workshop on 'Advancing research on Understanding Environmental Eects of UV lters from Sunscreens' for which the proceedings report has been released and can be downloaded free here. Nina Santos was selected to receive the Bill Huppert Endowed Student Award established by the Maryland Salt-water Sporishermen's Associaon (MSSA) Scholarship Foundaon in the amount of $1,522. This award provides merit-based awards for MEES graduate students.Ma Stefanak was selected to receive the 2023 Debbie Morrin-Nordlund Memorial Graduate Travel Award in the amount of $1,616. Michael and Nancy Morrin, Debbie’s parents, have established an endowment in her memory to fund MEES students to conduct research or to present their ndings at a naonal or internaonal conference.Jackie Grebmeier, Lee Cooper, Brian Marx, Nick Silverson and Chrisna Goethel spent July aboard the Canadian Coast Guard icebreaker Sir Wilfrid Laurier sailing from Victoria, BC, Canada to Utqiagvik, Alaska and undertaking eld work in the Bering and Chukchi seas as part of the Distributed Biological Observatory research project.During their cruise, Lee was able to capture a picture of the Shishaldi volcano erupng on Unimak Island.

Safety Corner: Routes of EntryThere are four points of entry by which chemicals can enter the body – absorpon through the skin and eyes, inhalaon, ingeson, and injecon. You can decrease or eliminate your exposure to them by taking measures to protect yourself and your co-workers. The rst thing you should do is to always read the Safety Data Sheets (SDS) for the chemicals you will be using. Remember to clean up aer yourself and report any spills. You should also be wearing the appropriate personal protecve equipment (PPE).Absorpon through the skin and eyes This is the simplest way for chemicals to enter the body. The skin is made up of hair follicles, sebaceous glands, and sweat glands which are abundantly supplied with blood vessels that help to promote the absorpon of chemicals. The skin also has a keran layer which contains fat and fat cells which can make it easier for solvents and other organics to pass through the skin. Once the chemical enters the bloodstream, it can cause injury to other organs. Chemicals can also enter the skin through cuts and abrasions or if the skin is very dry and cracked. Injuries can range from redness and mild dermas to serious burns and destrucon of skin ssue. If exposed, ush the injured area with water for 15 minutes and remove any contaminated clothing. The eyes are another avenue for the absorpon of chemicals into the body. Some chemicals, such as corrosives and phenol, can cause a very painful injury or blindness. The eyes also have a vascular system that can aid the absorpon of some chemicals into the bloodstream and then to other organs. If chemicals get into the eyes, ush the eyes for 15 minutes at an eyewash staon and get medical aenon if necessary. In order to avoid these types of injuries, please be sure to wear the appropriate personal protec-ve equipment – lab coat, gloves, and goggles. Inhalaon This involves gas and vapors, dust, fumes, and smoke. Chemicals are capable of passing through the mucous membranes in the mouth, throat, and lungs and into the bloodstream. The lungs have a very dense capillary system through which they can pass very quickly. The degree of injury will depend on the toxicity of the chemical, its concentraon, its solubility in ssues, and the dura-on of exposure. There are instances where an injury is not acute or readily apparent but may occur slowly over a long me. The olfactory system in our nose can become desensized to smells to the point where we may not realize we are inhaling anything. Some chemicals such as mercury are cumulave poisons. They can cause damage from small concentraons being inhaled over a long period of me. If there is an incident in the lab, get the vicm to fresh air. When working in the lab, be sure to have adequate venlaon or work in a hood and if necessary use a respirator.Ingeson Chemicals can be absorbed through the digesve tract. This does not usually occur because someone ate chemicals, but because contaminated food was ingested or someone touches their mouth with contaminated hands. It is also possible to have chemicals trapped in lip balm or chewing gum. Once chemicals enter the digesve tract, they can pass through the intesnal wall and into the bloodstream. Acids and bases can cause severe burns in the throat and stomach. If someone has ingested chemicals call Poison Control. Do not induce voming unless directed to do so by a physician. In order to avoid this situaon, do not store food and bev-erages in the laboratories. Do not perform any pipeng or siphoning by mouth. You must also remember to wash your hands aer working in the lab and before eang. Injecon Chemicals can enter through accidental injecon by a syringe or being cut by a contaminated piece of glass or metal. If this occurs, wash the area with soap and water. In all of these instances, if it is necessary, please get medical aenon.Referenceshps://ehs.unl.edu/documents/tox_exposure_guidelines.pdfhps://www.ccohs.ca/oshanswers/chemicals/how_chem.htmlhps://www.clemson.edu/research/safety/manuals/labSafety/exposureRoutes.htmlhps://ehs.princeton.edu/book/export/html/60P:\SAFETY\PLANS & POLICIES\RTK Training Docs4

UpdatesFisheries Resource Monitoring (FRM)• Our newest FRA and oshore survey kingpin, Evan Kostelecky, began work at the end of June. In true TailWinds fashion, his rst days were spent on the F/V Integrity• Commercial sh pong surveys have been completed each month since April and will connue through November• Recreaonal angling surveys started in June and will connue through September.• We struck black seabass gold in early June. We’ve now reached the summer doldrums, where we’ll likely remain for the remainder of the season.Real me whale monitoring• The migraon season for baleen whales oshore Ocean City, MD 2022 - 2023 concluded in April 2023. Protected humpback whales, endangered n whales and crically endangered North Atlanc right whale were all detected by the real-me whale buoy (RTWB). • Humpback whales were the last species detected on April 26, 2023 (see image below). Humpback whales create the most varied sounds out of the 4 baleen whales species idened by the RTWB, oen idened by song paerns, such as the low frequency downsweeps seen below.
