CHESAPEAKE BIOLOGICAL LABORATORY | SOLOMONS, MDSEPTEMBER 2022ISSUE 73Lab Lines1IN THIS ISSUE:DIRECTOR’S VIEW235Signs that the seasons are changing: long sleeves and the awful pumpkin spice in everything. Even cheerios! At CBL, the turning of the season brings new opportunities. Look for information shortly announcing the Science for Communities lecture series. Over ve Tuesday evenings, starting on October 18th, CBL faculty and FRAs will be presenting our work in hybrid lectures that will oer locals the opportunity to join us in person in BFL 1101 and those further from the lab to join via zoom as they have done over the last two years. Autumn has also brought the return of our distinguished speaker seminar series, which will be in person on Wednesdays at 3:30 in BFL 1101. Seminars are listed on the CBL calendar (instructions at https://handbook.cbl.umces.edu/home/good-to-know/cbl-community-events), and on the UMCES web page. We have a diverse array of speakers and topics – from engineering water systems to spatial ecology and from post-docs to senior faculty. Our speakers come from local academic partners, such as St Mary’s, HBCUs such as Coppin State and from the NGO world. I encourage all to attend the seminar, and stay for the reception afterwards. There will also be a lunch for the speaker with students and FRAs. Also returning is the Friday Informal Lunch Lecture (FILL) in which we will hear about emerging research and talk about professional development. Finally, Bagel Monday is back. It will be every other Monday (Oct 10, 24, Nov 7, 21, Dec 5, and Dec 19). It is also on the CBL calendar.Finally, September 29 is sta appreciation day at UMCES. Each lab will celebrate sta with a catered lunch following presentation of the President’s Outstanding Sta Award. I encourage everyone to thank a member of sta for all that they do to make working at CBL so positive. Without them our grants wouldn’t be submitted, our pay cheques wouldn’t be deposited, our grounds wouldn’t look fantastic and our buildings wouldn’t operate.OUTREACHIN CASE YOU MISSED IT/ PUBLICATIONS4SAFETY CORNER6WELCOME TO CBL

A professional photographer onboard, Leonard Sussman, is posting photos and a blog at leonardsussman.com Carys Mitchelmore presented a seminar on sunscreens and ocean/coral safety at the Society of Cosmetic Chemists Symposium on September 8th 2022 in West Orange, New Jersey. A new National Academies of Sciences, Engineering, and Medicine report, that Carys Mitchelmore was a committee member on, was recently released and highlights that the "EPA Should Conduct Ecological Risk Assessment of UV l-ters found in Sunscreen to Understand Their Impact on Aquatic Environments”.

Welcome to CBL!With the new semester comes many new faces to CBL's campus. Please welcome the following new CBL students! Six new interns have joined the CBL Environmental Education Community College Collaboration (E2C3) program that oers internships to qualifying community college students interested in pursuing environmentally-based Science, Technology, Engineering, and Math (STEM) careers. Our students for the fall 2022 semester include:CBL also welcomes new postdoc Dr. Zhi Yang Soon (zsoon@umces.edu) to Dr. Mario Tam-burri's lab. Dr. Soon, who received his PhD earlier this year from the University of Science and Technology (Republic of Korea) and Korean Institute of Ocean Science and Technol-ogy (KIOST), will be working on the characterization and impacts of microplastics, and other contaminants, released from commercial ship coatings.

Dry ice is a solid form of carbon dioxide that is used for cooling. Carbon dioxide is a solid at a temperature of -109° F (-79° C) and it will sublimate from a solid to a gas at any temperature greater than -109° F. It is colorless, nonammable and comes in ake, pellet and block form. One pound of solid dry ice will produce 250 liters of carbon dioxide gas.StorageBe sure to store dry ice in a well ventilated area. It should not be stored in walk-in refrigerators, environmental chambers or cold rooms.Dry IceDo not store dry ice in a sealed container. Pressure can build up in the container and explode at room temperature. It must be stored in a loosely lidded package that allows for some release of CO2 gas. Styrofoam is the best container. Dry ice will sublimate at the rate of ve to ten pounds each 24 hours (for pellets or chips), so if you won't be using the dry ice right away, plan for the loss of product.Disposal Do not dispose of in a trash can, sink or toilet. It is best to leave container opened in a well ventilated area. HandlingWhen using dry ice, be sure to wear thermally insulated gloves, eye protection and a lab coat. Use tongs to handle the ice. Never handle with bare hands. First AidIf skin comes into contact with dry ice, remove any clothing not frozen to the skin. Do not rub the body part and do not use dry heat to warm the skin - tissue damage could result. Place the aected part in a warm bath. If it is inhaled, get the victim to fresh air and place in a comfortable breathing position.If the eyes are aected, ush eyes for 15 minutes and consult an ophthalmologist.https://www.thoughtco.com/how-to-handle-dry-ice-safely-606403https://www.safety.rochester.edu/ih/dryicehandle.htmlhttps://www.airgas.com/msds/001091.pdfdryice.pdf (washington.edu)
