CHESAPEAKE BIOLOGICAL LABORATORY | SOLOMONS, MDAPRIL 2022ISSUE 68Lab LinesDIRECTOR’S VIEW1IN THIS ISSUE:DIRECTOR’S VIEW235April has seen the lab emerge from COVID restrictions, with people becoming more active in research planning and activities. We have started to see more people engage in research cruises and attend scientic meetings, some are even beginning to travel internationally. We are looking forward to new students, REUs and interns joining us this summer. This time of year is also a period when we bid farewell to people. We congratulate Ben Frey and Meg Munkacsy for defending their MS theses - and wish Alex Robillard all the best for his dissertation defense on April 29 at 1 pm.We are re-engaging with the community. We have completed our Science for Communities lecture series that focused on the Urban Ocean - with thanks to Mario Tamburri, Andrew Heyes and Jeremy Testa. All of the lectures are available on CBL’s website. We are planning to re-open the Visitor’s Center. We will not have time to retrain a cadre of docents to sta the Visitor’s Center, so I am asking members of the CBL community to volunteer. I am looking for people to volunteer on Friday afternoons from 1-4:30, Saturdays from 10-1 and 1-4:30 and Sundays from 10-1 and 1-4:30 on all weekends from May 27 - July 31. You can select a specic day and time slot to volunteer. I will make a random draw from all those who volunteer to award prizes, such as T-shirts, and gift gift cards at restaurants. You can sign up at https://calendar.google.com/calendar/appointments/schedules/AcZssZ2Vs9hynUnMxtrQrUXLXI41kUvP5mgnjBCCTXxrWO_nymhrUevpGOtNi5mi8nXZm12ZiUZXQr8yAs we emerge from COVID, I want to hear what is on your minds. So starting from May 6th and most Fridays thereafter (details in the CBL calendar), I will set up my laptop and work over a pot of tea in Nice Hall at 3:00 pm. If something is on your mind that you would like to discuss, come and join me. If you would like to discuss something in condence, please let me know and we can meet in my oce in Nice Hall. This oer is open to everyone - sta, students & faculty. OUTREACH/PUBLICATIONSIN CASE YOU MISSED IT4SAFETY CORNER

In Case You Missed ItNicholas Coleman received the inaugural Atlantic Cooperative Telemetry Network/MARACOOS Conference Award ($1000) given to students undertaking marine and estuarine animal telemetry studies to attend related scientic meetings.Lee Cooper and Jackie Grebmeier traveled to Tromso, Norway for the annual Arctic Science Summit Week meeting sponsored by the International Arctic Science Committee (IASC). They participating in meetings of the Marine Working Group of IASC, the Pacic Arctic Group, and workshops relating to the Synoptic Arctic Survey, the Arctic Action Plan of the UN Decade of Ocean Science for Sustainable Development, and development of an Distributed Biological Observatory in the European Arctic, modeled on the UMCES-led National Science Foundation project in the Bering and Chukchi Seas. Prior to returning home, they also visited former student Christina Goethel (who also traveled to Norway in her capacity as a new IASC Fellow) in Akureyri, Iceland and participated in a class she is teaching this semester in Iceland.

Continued: In Case You Missed ItComing this spring, additional EV level II charging stations! With funding assistance from the Maryland Energy Administration Electric Vehicle Supply Equipment Rebate Program we will be installing six new EV charging stations in the BFL parking lot. If you are interested in installing a charging station at home this program is available for residential projects as well. The residential program can provide a rebate of 40% up to a maximum of $700 per charging station installed.Link for more information: https://energy.maryland.gov/transportation/Pages/incentives_evserebate.aspxCBL’s John Grin and Chris Turner are currently attending courses to gain their Fundamentals of Energy E-ciency certication. This has been made possible by a grant program through SMECO that covers the majority of the certication costs. Thanks John & Chris for taking the time to enhance your skills and continue our path to making CBL as ecient as possible. Congratulation to Benjamin Frey, who successfully defended his thesis defense for the MEES Progam M.Sc. enti-tled “Validation of Age and Growth Using Microconstituent Analysis of Fish Hardparts” on April, 14th.

Safety Corner: Oven Safety - Cheryl Clark1. The rst thing you should do is to read the manual to know how to operate the oven. 2. Be aware of what you are doing and follow safety procedures. 3. Do not use an extension cord to connect an oven to a plug. 4. Never use laboratory ovens to prepare food for human consumption. 5. Do not use household ovens in the laboratory. While laboratory ovens have their heating elements separated from the interior of the oven, household ovens do not.6. Inspect oven prior to use. The oven should be clean and free of spills, residue and debris. 7. Make sure the oven is working properly and the cord and plug are in good working condition. If there are any problems, do not use the oven and label it to warn others from using it. 8. Make sure the oven temperature is correct. Do not use a mercury thermometer to calibrate ovens. Breakage can cause an accidental spill and exposure to mercury.9. Use the right oven for the task. You need to consider the temperature range that is needed and what is the maximum safe working temperature for the material involved. 10. Be sure to check the materials before placing them into the oven. Do not put plastics, ammables or combustibles in regular laboratory ovens. These can melt or ignite, spreading re and/or fumes into the lab. 11. Do not use ovens to dry any chemical sample that might pose a toxic hazard unless special precautions have been taken to ensure continuous venting of the atmosphere inside the oven. Volatile substances can become airborne and expose personnel to harmful fumes. Any glassware should be rinsed with distilled water before going into oven to remove any chemical residue. 12. Make sure there is airow around the samples when packing them in the oven. Do not pack them tightly to get as many as possible in. 13. Wear the appropriate personal protective equipment. There is a potential burn hazard from the hot surfaces of the oven and the contents. If steam is released from the oven, be sure to step behind the oven door when opening.References:https://www.labmanager.com/product-focus/how-safe-is-your-lab-oven-2798https://www.labmanager.com/lab-health-and-safety/laboratory-oven-hazards-6724https://www.bu.edu/researchsupport/forms-policies/lab-equipment-dryerovenwasher-safety-guidelines/https://ehs.princeton.edu/node/376Prudent Practices in the Laboratory 2011.

Science for CommunitiesThe Science for Communities lectures in our “Urban Ocean” series has concluded for Spring 2022. Visit our webpage to see recordings of our past speakers: https://www.umces.edu/cbl/science-citizens-videos. CBL Visitor CenterThe Chesapeake Biological Laboratory Visitor Center will reopen Memorial Day Weekend! Reopening our Visitor Center after two years of closure is a signicant eort. Work is underway to create new, child-friendly exhibits for the aquarium room. Promotional materials are also being updated. Thank you to the facilities team and to the IT team for their ongoing help preparing the Visitor Center for our. In preparation for reopening, we recognize that training of returning docents and the recruitment and onboarding of new volunteers will take time. Volunteer support from members of the CBL community during the initial reopening of the Visitor Center would be tremendously helpful. If you are willing to volunteer in the Visitor Center, please email Outreach Coordinator Sarah Brzezinski at brzezins@umces.edu.
