Dr. Logan is an Associate Professor in the School of Natural Sciences at California State University, Monterey Bay. Her research focuses on the physiological mechanisms that marine animals use to survive in their environments, from the biochemical to the whole organismal level. In the face of climate change, understanding the mechanistic basis for why species ranges are shifting is fundamental to predicting which species will be the “winners” and “losers” in our changing environment. She studies how ecologically important fish and invertebrates regulate their physiology in response to temperature, hypoxia and ocean acidification associated with climate change.

Cara Wilson is a satellite oceanographer for the Environmental Research Division (ERD) at NOAA’s Southwest Fisheries Science Center in Monterey CA and is the PI of two regional nodes of NOAA’s CoastWatch program – the West Coast Regional Node and PolarWatch, which are both housed at ERD. Her research interests are in using satellite data to examine bio-physical coupling in the surface ocean, with a particular focus on determining the biological and physical causes of the large chlorophyll blooms that often develop in late summer in the oligotrophic Pacific near 30°N. She received a Ph.D. in oceanography from Oregon State University in 1997, where she examined the physical dynamics of hydrothermal plumes. After getting her PhD she worked as the InterRidge Coordinator at the University Pierre et Marie Curie in Paris, France. Her introduction to remote sensing came with a post-doc at NASA’s Goddard Space Flight Center which involved analyzing TOPEX and SeaWiFS data. She joined NOAA in 2002 and has been active in increasing the satellite usage within the National Marine Fisheries Service. She is also the treasurer for PORSEC (Pan Ocean Remote Sensing Conference) and the current chair of the IOCCG (International Ocean Colour Coordinating Group).
Kevin is a biological oceanographer at Stanford University. He studies the microbial ecology of polar ecosystems to better understand their role in marine food webs, nutrient cycling, and productivity. His research focuses on photosynthetic organisms living in the sea ice and the ocean and how they are able to thrive in such extreme polar conditions.
Recent observations contradict the paradigm that waters beneath the consolidated Arctic Ocean ice pack harbor little planktonic life. However, high concentrations of phytoplankton biomass beneath Arctic sea ice have been reported in areas as widespread as Resolute Bay, Baffin Bay, the Barents Sea, the Laptev Sea, and the Chukchi Sea. The largest and most well documented of these under-ice blooms was observed in the Chukchi Sea beneath fully consolidated sea ice. At its peak, the algal biomass associated with this feature rivaled that of the most productive ocean ecosystems on Earth. It is likely that, in the present climate, under-ice blooms, while largely unaccounted for, are more prevalent and more productive than is presently understood. Because these under-ice blooms are invisible to satellite sensors, seasonally ice covered waters on Arctic continental shelves have the potential to support vastly higher rates of NPP than has been attributed to them in the past.

Dr. Maya Reimi is a paleoclimatologist and isotope geochemist. She received her PhD from Texas A&M University working with Dr. Franco Marcantonio. For her dissertation she used radiogenic isotope ratios (Nd, Pb, U, Th) to understand changes in dust provenance and ocean water masses in the central Pacific, over the most recent glacial cycles. She is currently a postdoctoral researcher in Ocean Science at UCSC, working with Dr. Christina Ravelo. Her current research centers around understanding the changes in the Indo-Pacific Warm Pool during the Pliocene and early Pleistocene, using Mg/Ca in foraminifera as well as oxygen and carbon isotopes to reconstruct ocean temperature, salinity, and ice volume changes.

Marine debris is one of the most widespread pollution problems facing the world's ocean and waterways. Huge amounts of consumer plastics, lost fishing gear, and other items lead to chemical and physical impacts on marine species and habitats, and socioeconomic impacts on coastal communities. With an estimated eight million metric tons of mismanaged plastic waste entering the ocean every year, everyone has a role to play in preventing debris at the source. This presentation will include an overview of this multifaceted issue and approaches to prevention, the state of the science on marine debris sources, fate, and effects, and a summary of current efforts in the field with a special focus on California.

Sediment and contaminant transport in urban wetlands is a complex problem requiring robust tools to characterize. Berry’s Creek in New Jersey is an urban wetland that has undergone a multitude of changes over the past century, many of which resulted in contamination posing unacceptable ecosystem risk. The presentation will outline the field and modeling studies related to the risk assessment and remedial investigation of the Berry’s Creek Study Area wetland. The study goals were to characterize the fate and transport of sediment-bound contaminants in the system. These perspectives are being used to develop remedial strategies that will help reduce the overall risk.

Various national and international media outlets have covered Mike’s scientific discoveries. His diverse research efforts are unified by a common goal: better understand how natural ecosystems work, so that we can better sustain the essential services these ecosystems provide to humankind. In addition to his scientific research, Mike is an award-winning science communicator with broad interests in connecting diverse swaths of the public with the process of scientific discovery and all that it offers to individuals and to humankind. The son of an Argentine immigrant, Mike was raised working class by a single mom and was a first generation college student. He knows all too well the barriers that prevent the economically disadvantaged from tapping into the STEM world. Thus, Mike founded and runs SciAll.org, which uses unconventional videos to diversify interest in and access to STEM. By bringing mass online audiences along for the adventures of his career, including run ins with sharks, whales and other underwater wonders, Mike aims to deliver the timely message that science is an exhilarating process of discovery that is truly accessible to all and in the service of all.
Through their presence and even simplest behaviors, animals produce sensory information that is publicly available to influence the behavior of surrounding individuals, even those from different species. While there is a wealth of evidence that social information can strongly affect the behavior, fitness and interactions of organisms, it remains largely unknown how this ubiquitous phenomenon may affect the ecology of the greater system. In this talk, centered on the behavior of mixed-species groups of fish in a tropical coral reef, I present work that integrates novel empirical and quantitative approaches to investigate the role that social information can play in the function and dynamics of natural ecosystems.

Natural variability in all aspects of the Earth system – including the climate system and ecosystems – presents a formidable challenge to the detection and quantification of change forced by industrial activities. Error in detection can disrupt concerted efforts to respond to the challenges of climate change, whereas statistically robust quantification informs our understanding of underlying mechanisms of change. The rate of observed climate change results from the superposition of mixed signals such as trends and shifts on variability arising from the memory within the climate system. Statistical methods used to characterize change in time-series must be flexible enough to distinguish these components. In this talk, I present a new methodology that is used to separate different modes of change from memory in global mean surface temperature records. This analysis clarifies a key point in the scientific debate related to the recent “hiatus” in warming. I also discuss the importance of considering memory timescales (i.e. short vs long memory), and highlight regions in the ocean where the routinely assumed short-memory assumption may be problematic and affect detection.
