“Mother Nature is not happy right now and she’s trying to tell us, in many ways,” says Kimberly Prather, Professor of Climate, Atmospheric Science, and Physical Oceanography at UC San Diego.
New weather patterns and events are causing concern but how do we know these changes are caused by human activity? Climate scientists are looking at trends over time to determine our impact on the planet.
Prather discusses recent CAICE studies aimed at advancing our understanding of how the oceans influence human and planetary health including novel experiments being conducted in a unique ocean-atmosphere simulator.
Watch — How Do We Know Humans are Impacting the Health of Our Planet? – Exploring Ethics
Ours is a water planet. Technology is shaping our uses, both as foe and ally. It has made humans the dominant predator and provides us food, gives us half the oxygen we breathe and created many maritime jobs. But technology has also raised CO2 levels, caused acidic oceans, threatened ocean biodiversity and created grand climate challenges.
Marine biologists like Doug McCauley at UC Santa Barbara are also using technology to promote ocean health and provide a balance. In this talk, McCauley describes examples of technology used to help the oceans and marine biodiversity. He shows systems that track whale activity and communicate it to ships so they know where to slow down to avoid collisions. He describes technology to monitor marine protected areas, image recognition techniques to study the endangered giant sea bass and electronic tags to follow sharks.
McCauley began his career as a fisherman in the Port of Los Angeles. Eventually he migrated to marine science and UC Santa Barbara. McCauley has degrees in political science and biology from the UC Berkeley. His PhD research was done at Stanford University where he studied the ecology of sharks, giant parrotfish, and coral reef ecosystems. McCauley’s science is motivated by the belief that we must better understand how complex ocean ecosystems work if we want to better protect them from threats like overfishing, climate change, and pollution.

The vastness of the ocean is only surpassed by the biodiversity within it; from familiar and unfamiliar mega-fauna, to every microbe and virus inhabiting every corner of the seas – from the deep freeze of the Antarctic to the scorching plumes of volcanic seafloor vents.
Paul Jensen describes how he and other researchers are tapping into the biodiversity of the world’s oceans as a relatively new resource for natural product drug discovery. Jensen is at the Center for Marine Biotechnology and Biomedicine at Scripps Institution of Oceanography, UC San Diego.

The Arctic is changing rapidly in response to global climate and economic activity and yet much of it remains unexplored with modern scientific techniques.
Jeff Bowman is a biological oceanographer who studies marine microbial communities. In this presentation at the Birch Aquarium at Scripps Institution of Oceanography he describes his group’s work in the Arctic as they seek to understand the ecological implications of changing sea ice conditions.
They are also preparing to participate in the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) Expedition, an unprecedented multi-national effort to study the high Arctic across a complete seasonal cycle.

Kelp cutters once harvested tons of the nearshore kelp off the San Diego County coastline, producing additives for your ice cream, beer and pharmaceuticals.
And of course, anyone who has had a California Roll or a bowl of miso soup is familiar with the centuries-old use of Nori.
But now Scripps researchers are working to uncover other value from the ubiquitous red, green and brown algae that thrives in our waters, even exploring the use of seaweed to reduce methane produced by dairy cows – and perhaps even improving their health and productivity.
Join Scripps Oceanography’s Jennifer Smith and entrepreneur Brant Chlebowski as they tell the story of their collaboration on applied aquaculture research that has sparked the formation of the California Seaweed Company.
