CHESAPEAKE BIOLOGICAL LABORATORY | SOLOMONS, MDMARCH 2022ISSUE 67Lab LinesDIRECTOR’S VIEW1IN THIS ISSUE:DIRECTOR’S VIEW23I cannot begin to tell you how excited I am about the coming months as we engage more fully with our science and our CBL community and beyond. On Tuesday, we start our Science for Communities seminar series that will focus, this spring, on the Urban Ocean. The improvements in the COVID status have occurred too late for us to switch to in person – so please register and attend the seminars over Zoom. Details are available at https://www.usmf.org/s4c/. April will see the return of Bagel Mondays – albeit that the rst one will be on a Wednesday (April 6th). It has been two years since we gathered in this way. I am also trying to line up a couple of in person seminars – details to follow. Finally, we will open the Visitor’s Center on May 27th, and we will participate in the rst Bernie Fowler Wade-In on June 12. This will be the rst Wade-In following Bernie’s death and I suspect it will be well attended. I will keep a close eye on the viral case rates and will alter plans accordingly if the health conditions require it, but until then, I am looking forward to seeing people around the lab.

In Case You Missed ItLora Harris is now serving as an Ambassador for AGU’s new LANDInG Community of Practice. This is an online space intended to welcome, support, and connect current and aspiring champions of justice, equity, and inclusion eorts in the geosciences. Please consider joining: https://connect.agu.org/landingcop/homeWith support from the JES Avanti awards, Dr. Dave Secor has been working on telemetry research in the Chesapeake Bay and was recently featured in a NOAA news article titled, “Tracking Fish in the Chesapeake Bay Helps Researchers and Resource Managers”. Click here for the full article - https://www.sheries.noaa.gov/feature-story/tracking-sh-chesapeake-bay-helps-researchers-and-resource-managers. Lee Cooper, Jackie Grebmeier, Emma Green, Laura Gemery, and Andrea Pfa all contributed separate presentations at the online Ocean Sciences Meeting that was sponsored by AGU, ASLO, and TOS. The presentations were recorded and will be uploaded to the lab website. Jackie also helped lead a town hall presentation of the Synoptic Arctic Survey program for a large audience.Helen Bailey attended and presented at a Passive Acoustics Monitoring virtual workshop hosted by the Bureau of Ocean Energy Management (BOEM) on 7-9 March 2022.The CACB planning is underway. The design team is working on designing the space to meet the requirements of the approved program document and to provide an outstanding space for UMCES. Sustainable features have been identied, a preliminary development of a landscaping plan and the IT infrastructure has been discussed and is in the design process. Stay tuned as this building becomes a long-awaited reality!CHESAPEAKE ANALYTICS COLLABORATIVE BUILDINGUMCES 10SITE DIAGRAM
Safety Corner: Radiation Safety - Cheryl ClarkWe are exposed to some form of radiation every day in our environment from the sun, stars, soil, rock, and air. However, there are also man-made sources which are very helpful tools in the laboratory and exposure to these must be strictly controlled. If you need to work with radioactive materials, please remember that no one may use, bring or remove any radioactive devices or materials without the approval of the radiation safety ocer and the radiation safety committee at College Park. There are two types of radiation - ionizing and non-ionizing. Non-ionizing examples are heat, radar, microwaves, and radio waves. This type of radiation deposits energy in the materials that it passes through. It can heat substances, but there is not enough energy to remove electrons from atoms and molecules. Ionizing particles deposit energy to break molecular bonds and create charged particles and are capable of damaging plant, animal and human cells.There are four basic types of ionizing radiation:1). Alpha particles – minimal health eect – large slow-moving particles – cannot penetrate outer layers of skin or paper. Hazard only if inhaled, injected or ingested. 2). Beta particles – medium health hazard – higher levels of energy than alpha particles. Can harm living cells by breaking chemical bonds and forming ions. Acute and chronic eects occur when these particles lose energy by colliding with tissue inside the body causing damage.3). Gamma particles – high health hazard - travel at speed of light with enough energy to penetrate the body exposing all organs to damage.4). X-rays – high health hazard – enough energy to penetrate tissue.ALARA Policy – at all times the amount of radiation received by an individual is to be kept As Low As Reasonably Achievable. An employee’s exposure can be minimized by shielding the source and themselves. Their exposure should be kept to a minimum amount of time and there should be emergency alarms and evacuation procedures in place. The distance between the person and the source should be maximized and if necessary, robotics or remote operations should be used.Storage - Any radioactive material or radiation-producing device are to be kept in a locked restricted area. These areas are designated by radiation symbols (shown above) which should be posted on the outside door of the laboratory.Excerpted from: Hazard Communication Right to Know OSHA 29 CFR 1910.1200 COMAR 09.12.33National Research Council.

Science for CommunitiesScience for Communities is a public lecture series that engages non-scientic audiences in learning about environmental research and the important work being done at the Chesapeake Biological Laboratory. They are also a great opportunity for CBL faculty, sta and students to learn more about each other’s work. The Spring 2022 Science for Communities Series, themed around “The Urban Ocean,” will be hosted as Zoom webinars. All are welcome to attend these hour-long programs.
