Message CHESAPEAKE BIOLOGICAL LABORATORY I SOLOMONS, MDISSUE 101Lab Lines January 20251Directors ViewFirst Happy New Year, here’s to a happy, healthy and prosperous 2005. Andyes that means it is finally here - the 100th year anniversary of the ChesapeakeBiological Laboratory, the oldest state supported marine laboratory on the EastCoast, USA. We have much to celebrate and recognize how instrumental CBLhas been in understanding and protecting our natural resources in theChesapeake Bay and beyond and in training our next generation ofenvironmental leaders. It is thanks to the dedication of the faculty, scientists,and students past and present that solutions are being provided to addressenvironmental problems, that new insights into fundamental science haveevolved and novel tools and approaches have developed. Our support staffhave been instrumental in helping our scientists achieve their goals, andmaintaining a safe and productive workplace.Our UMCES centenary celebrations kicked off here at CBL on January 24thwith the banner unveil and UMCES logo for 2025. Many distinguished guestsjoined us, including Secretary Flora, our Calvert County Commissioners andthe Director for Calvert County Economic Development, representatives fromSenator Van Hollen’s office, emeritus UMCES President Don Boesch and veryfittingly, Dr. R.V. Truitt’s grandson. I want to thank you all for attending,especially those of you who presented posters and displays showcasing someof our current research, educational and community activities and also thosewho helped setup the event. There will be many more opportunities throughoutthe year at UMCES and CBL to mark this historic event, stay tuned!January 27th was also the start of the Spring semester, I wish all our studentsa joyful learning experience as they work towards completing their graduatestudies. 2025 is also an exciting time of change across UMCES leadership,with new unit Directors at CBL and IMET. Stay tuned for more details on theseand UMCES and CBL 100 year activities, suggestions for CBL communityevents are also always welcome.IN THIS ISSUEDirectors View1100 Year Kick-off2In Case YouMissed It3-4Publications 5Wave of Plastics5In the News6Safety Corner7

Happy 100th Birthday Chesapeake Biological Laboratory!UMCES kicked off the celebration of its 100th anniversary with a centennial launch event at CBL on January 24th 2025, appropriatelyin the laboratory named after our founder Dr. Reginald V. Truitt. The event attended by CBL and UMCES employees and manydistinguished leaders and guests included celebratory remarks from Carys Mitchelmore (CBL Interim Director), Rebecca Flora (Stateof Maryland Secretary of Planning), Buddy Hance (Calvert County Commissioner) who also presented CBL with a citation to markthis momentous occasion, and Fernando Miralles-Wilhelm, UMCES President. As we reflect on the past 100 years, we are reminded of the countless contributions that the Chesapeake Biological Laboratory hasmade. Our scientists have delved deep into the complexities of our natural world, uncovering insights that have shaped ourunderstanding of fisheries management, water quality, ecosystem restoration, biodiversity, and the broader impacts of human activityon the environment. The laboratory’s work has not only advanced the frontiers of science, educated our next generation ofenvironmental leaders, brought together multiple stakeholders and the community to engage in the shared responsibility ofpreserving our environmental for future generations, and directly informed policies and practices that protect and restore theChesapeake Bay—one of our nation’s most cherished and vital ecosystemsThis centennial celebration serves as both a tribute to our past and a call to action for our future. Together, we will continue to inspire,to innovate, and to lead in the quest for a sustainable and thriving planet.This was a great start to our yearlong celebrations. Stay tuned for more events!2

See the official NOAAannouncement here: https://www.fisheries.noaa.gov/feature-story/noaa-helps-students-and-educators-dive-environmental-education The "Wave of Plastic, Jr." MWEE program is an exciting adaptation of our successful middle school "Waveof Plastic" program, tailored specifically for 5th-grade elementary school students. We would like toacknowledge and thank all of the many UMCES, UMD, SMCPS, and CCPS collaborators that spent yearstirelessly building the original middle school "Wave of Plastic" program that laid the foundation for this"Wave of Plastic Jr." edition. This new edition engages younger learners and their educators in understanding the impact of plasticpollution on aquatic ecosystems. Through hands-on activities, inquiry-based learning, and real-worldinvestigations, participants explore the journey of plastics in the environment and discover actionablesolutions to protect our watersheds.This initiative embodies our mission to inspire the next generation of environmental stewards througheducation and action. By introducing elementary students to these critical concepts, we’re fostering alifelong commitment to environmental health.We’re excited to see the ripple effects of this funding in our communities. Stay tuned for updates as webring this program to life! Together, let’s make waves for a cleaner, healthier environment!Wave of Plastic: Jessica McGlinsey

The Laboratory Safety Institute’s (www.labsafety.org)Golden Rules of Chemical Fume Hood Use1. Make sure the fume hood is working.2. Keep the sash down except when working in the fume hood.3. Raise the sash only the minimum needed to perform the work.4. Work six to eight inches inside the plane of the sash.5. Keep the hood area clear and rear vent unobstructed.6. Raise equipment off the hooded deck. Use PVC pipe donuts (not wood).7. Remove flammables and unnecessary stuff.8. Understand the limitations.9. Check/inspect operation at least annually; sash cables every 2-3 years.10. Wear Protective Protection Equipment (PPE).11. Run cords, cables, and tubing under the air foil.12. Move arms slowly in and out of the hood.I would also like to add – please do not stick your head, neck and shoulders intothe hood. The sash is very heavy and supported on cables that can break. If theydo break, the sash will come down hard and is capable of breaking bones anddislocating shoulders.WWW.UMCES.edu/cbl I 410-326-4281P.O.
