Abstract
In recent years the Gulf Stream system has been observed to undergo changes at both the climatological and synoptic time scales. The Stream has been proposed to be slowing (Caesar et al., 2021; Piecuch, 2020), the destabilization point has moved westward (Andres, 2016), and the number of annual Warm Core Ring formations has doubled after the year 2000 (Gangopadhyay et al., 2019). These changes within the Gulf Stream system have large implications for large-scale climate phenomena as well as impacting local ecosystems and coastal communities. Through this work I propose to address three main questions regarding the Gulf Stream system and its rings, each with distinct spatial and temporal scales. The first question focuses on the Gulf Stream system as a whole, examining ring formation and instability processes within the Stream. This section aims to answer the question of what drives the Stream to form a Warm versus a Cold Core Ring. Preliminary results have found several asymmetries in ring formation between Warm and Cold Core Rings at both seasonal and interannual time-scales (Silver et al., 2021a). Additionally, a Gulf Stream North Wall forecasting model was created (Silver et al., 2021b) using wind and buoyancy forcing from the previous three years. Future work will use sea surface satellite tracks and ARGO floats to examine the Stream instability processes (baroclinic and barotropic) to see what drives the observed asymmetries. To address the second question, we follow a Warm Core Ring as it moves through the Slope Sea along the Ring Corridor. This section aims to understand how ring characteristics change with age and location. Using ARGO floats and a newly generated Warm Core Ring Tracking dataset, ring properties at depth can be examined as they travel throughout the Slope Sea. The third question is focused on characterizing the impact of a Warm Core Ring hitting the shelf break. When a Warm Core Ring hits the shelf several exchange processes can occur such as shelf streamers, salinity maximum intrusions, and Pinocchio's nose intrusions. These processes can push warm salty water onto the shelf, or pull cold fresh water off the shelf. The impact of these exchange processes on Zooplankton populations will be examined using ECOMON and ARGO data along with the previously mentioned Warm Core Ring tracking dataset.

Biology Department Seminar, Nick Dorian, "Do bees hedge their bets?"
- Location: > See description for location
- Contact: Biology Seminar Series
- Description: Location: LARTS 108
Abstract: Many organisms, from copepods to plants to bees, hedge their bets through prolonged dormancy, spreading offspring emergence across multiple years instead of just one. At first, though, its puzzling why prolonged dormancy is so widespread since the short-term costs of foregoing reproduction can be high. Only in sufficiently variable environments are the benefits of reduced variance in fitness outweighed by costs of lower short-term reproduction. These predictions arise from a vast body of bet-hedging theory, but only a few examples from desert annual plants demonstrate the adaptive value of prolonged dormancy in the real world. In this talk, I examine whether solitary bees (important pollinators in ecological and agricultural systems) also hedge their bets via prolonged dormancy. I use a combination of field data, mathematical simulations, and lab experiments to understand the adaptive value of prolonged dormancy in wild bees and the environmental factors that give rise to dormant offspring. My work gives us a glimpse into how a group of declining insect pollinators will fare under future environmental conditions and helps to resolve the extent to which ecological theory reflects the real world.

2020 - 2021 Multidisciplinary Seed Fund Presentations
- Location: > See description for location
- Contact: > See Description for contact information
- Description: The Offices of the Provost and Research Development are pleased to announce that the Annual Presentation for the 2020 and 2021 Internal Seed Funding Awards is scheduled for Friday, November 12, 2021 from 1:00 p.m. - 3:00 p.m. in the Grand Reading Room at the Claire T. Carney Library in Room 122.
The goal of this program is to provide seed funding for projects that involve areas relevant to institutional research priorities and have the potential to attract significant external funding. The seed funding is a one-time award to facilitate faculty research and collaborations and to help faculty improve their chances of external funding success.
Dr. Michael Goodman, Acting Provost and Vice Chancellor for Academic Affairs and Dr. Ram Bala, Vice Provost for Research & Academic Affairs will be overseeing this event. Please encourage your colleagues and students to attend this event to support the recipients of the 2020 and 2021 SEED Funding Awards and to learn about their research projects.

Online Teaching and Learning Strategies
- Location: Online
- Contact: CITS Instructional Development
- Description: A rigorous four-week, fully online certification course that introduces faculty to the current research and best practices for online teaching and learning. Using their own discipline-specific course materials for activities, faculty will work independently, collaboratively with peers from across campus, and with Instructional Designers to design and build one unit of online instruction in a myCourses site. This unit will meet the Quality Online Course Review Rubric criteria and be a model that faculty can reference and replicate as they continue to develop their upcoming fully online course(s).
