The confluence of the accelerating climate crisis, more frequent and severe disasters, widespread systemic injustice and oppression, and any number of additional coinciding crises paint a dark picture of our future. Climate professionals often feel inadequately trained to facilitate, navigate and lead communities through the transformative changes we all face. This program will offer directions on how these essential workers — and all of us — can grow the necessary skills and capacities to face and navigate our future. It is those very skills that may yet make us homo sapiens sapiens — “wise humans.” Series: "Jeffrey B. Graham Perspectives on Ocean Science Lecture Series" [Science] [Show ID: 38692]
As humans, we benefit immensely from the ecosystems around us — including the ocean — in obvious and not-so-obvious ways.

Why is the ocean — and this team of researchers — looking pretty in pink? For science! Scientists at UC San Diego’s Scripps Institution of Oceanography have launched the PiNC (Plumes in Nearshore Conditions) experiment to study the coastal zone where a river meets the ocean. Using a non-toxic, environmentally safe pink dye and a suite of instruments, researchers released the dye in the mouth of the Los Peñasquitos Lagoon at Torrey Pines State Beach near San Diego, California in the winter of 2023. Rivers and estuaries play an important role in delivering freshwater and materials such as sediments and contaminants to the coastal ocean, but little is known about how these plumes of more buoyant, fresher water interact with the denser, saltier and often colder nearshore ocean environment, particularly as the plumes encounter breaking waves. This experiment enables scientists to track the processes that take place when small-scale plumes of freshwater meet the surfzone.

Scripps Institution of Oceanography marine biologist Stuart Sandin illuminates his work leading the 100 Island Challenge, a project that uses high tech ecological surveys to capture snapshots of coral reef ecosystems found in the tropical waters of the Pacific, Caribbean, and Indian oceans. His team uses large-area imaging and 3-D visualizations to make unprecedented detailed observations of how coral reefs are faring. While some reefs are struggling, others have been able to adapt in response to changing climate and other human impacts. By combining ocean observation with modern techniques like genetic sequencing and data analysis, Stuart and his team aim to elucidate which corals are surviving and how. By decoding nature’s incredible capacity for adaptation, these scientists are paving the way for using this new knowledge to aid coral reef recovery.   Series: "Jeffrey B.

Coastal regions are susceptible to a host of threats to the natural environment and our quality of life as a result of climate change. Our beaches and coastal bluffs are being eroded by ocean storms and sea level rise, ongoing drought leaves us vulnerable to wildfires and habitat and wildlife loss, and our dependence on water from distant sources puts us at risk for severe water restrictions. Although climate adaptation and resilience planning already are underway in many communities, the threats associated with climate change make it increasingly important to design these efforts in ways that bring scientists, planners, practitioners, and community representatives together in planning processes. An expert panel is presenting how a cross-jurisdictional, interdisciplinary, collaborative approach leads to science-based and cost-effective strategies for building resilience in the face of climate change.

The Pacific footballfish is a large but rarely encountered deep-sea anglerfish known from only 31 specimens recovered worldwide. Strangely, over the course of last year (2021), three footballfish were found washed up on beaches in San Diego and Orange Counties. Scripps scientists aren't quite sure why these rare creatures are suddenly showing up on our beaches, but were lucky enough to collect, preserve and archive one of these unusual animals in Scripps world class oceanographic collections. This specimen, a true oddity, is now on display for a very limited time at Birch Aquarium. To see the footballfish and learn more about it, join us and Scripps Collections Manager, Ben Frable, for a deep dive into the fascinating story of this mysterious fish, where and how it lives, the biology of anglerfishes, and how Scripps scientists are preserving this animal for future research.

The ocean is enormous, indeed so large that for centuries we assumed that there was nothing we could do to substantially harm it. Unfortunately, we now know that this is not true. We are having success on some fronts, such as saving species from extinction, protecting ocean waters, fishing more sustainably, and restoring damaged ecosystems by replanting critical species and reducing pollution. Even actions on land, such as removing dams from rivers and rats from islands, can make an important difference to marine life. Of course, we still need to do much more, and do it faster. In the future, we can turn to new tools drawn from the natural and social sciences. Big data and genetic interventions have a role to play, as do ocean-based renewable energy sources and new financing schemes. Perhaps most important is the growing recognition that success depends on empowering local communities in efforts to create a healthier ocean.
