Wetlands are the link between land and water, and are some of the most productive ecosystems on Earth. They need our protection, for the commercial fisheries we depend upon, for the recreational opportunities they provide us, and for the benefit of the species that use them.
Within large timescales of glacial and interglacial periods, mini, rapid climate shifts may occur thanks to oceanic circulation processes and balancing global ocean budgets. The events in question originate in the North Atlantic; but, how do they affect the Antarctic?
Concerned for the future of science? I’ve highlighted a few things you can do to stay engaged in 15 minutes a day.
Research in marine renewable energy and climate systems will grow ever more important in the future. The research for these areas are not just done on the coast, however – I ventured into the mountains to learn more.
Paper: Letscher, Robert T., et al. 2016. Nutrient budgets in the subtropical ocean gyres dominated by lateral transport. Nature Geoscience, v.9: 815–819 If you were a marine organism looking for some grub, where could you find something nutritious? Nutrients in the ocean accumulate in the bodies of living things, which tend to sink to deeper waters […]
While the Earth’s mean surface temperature is slowly increasing, there are occasional, temporary slowdowns in the overall trend. The Interdecadal Pacific Oscillation, a strong, varying climate pattern, may be held accountable for the phenomenon.
Tropical Cyclones in the western Pacific Ocean have been intensifying in recent decades, but different data sets and methodologies made it hard to create accurate comparisons and models. Researchers adjusted these data sets to find that cyclones that make landfall are intensifying at faster rates than those that stay in the open ocean, and that the intensification is tied to rising ocean temperature.
Compared to the continents, oceanic crust is relatively young, less than 200 million years. But in a corner of the Mediterranean Sea, a remnant of the ancient Neo-Tethys Ocean lurks from the time of Pangaea.
At the International Marine Conservation Congress this year, I got a first-timer’s look into the world of marine conservation research and in-depth discussions about the future of conservation.
Paper: Claus W. Böning, et al. 2016. Emerging impact of Greenland meltwater on deepwater formation in the North Atlantic Ocean. Nature Geoscience, v.9: 523–527. We know the ocean is warming due to climate change. But did you also know there are huge paths that heat and energy takes through the global ocean? Although the ocean […]
I spent a morning learning about the Marine Mammal Center at Moss Landing in California, helped with the intake of a sea lion, and went out on a call with the team.
Ever wondered what your government does for the oceans? Here’s a brief glimpse.
While icebergs are calving from Antarctic glaciers at alarming rates, they may provide a negative feedback for the carbon cycle. Giant icebergs bring large amounts of iron to iron-poor areas of the Southern Ocean, stimulating primary productivity and boosting carbon sequestration.
While sardine stocks are seeing disturbingly low numbers along the US west coast, affecting fishermen and marine mammals that depend on them, scientists are working hard to provide forecast modeling and data than can better assist fishery managers to avoid this situation in the future.
Mountain ranges can actively evolve with Earth’s climate. A new study of the St. Elias Range in coastal Alaska demonstrates how dynamic and coupled our planet’s crust is to climate, and how we can investigate past erosion through marine sediments.
This week, I interviewed Joshua Jones, a Ph.D. student in biological oceanography at the Scripps Institution of Oceanography. The focus of his thesis research is marine mammals in the Arctic, their acoustic behavior and relationships with sea ice, and the effects of human activities on the underwater acoustic environment.
I attended the annual meeting for the Geological Society of America as a first-timer, joining scientists, educators, policy-makers, industry buffs, and students from the international community at the second-largest geology conference in the United States. I had attended a geology conference before, but I had not been involved to the extent that I was at GSA. The conference provided me with so much more than just a platform to speak to a wide audience.
At Geosciences Congressional Visits Day, 2015, I joined a diverse group of over 60 geoscientists that gathered in Washington, D.C. to learn how to speak to policymakers and how to craft our message requesting continued strong federal support for earth sciences.
The Chesapeake Bay region is a densely populated area, and also experiences more rapid sea level rise than anywhere else along the North American Atlantic Coast. Why? Scientists look to the lithosphere for answers, finding that the subsidence of an ancient lithospheric bulge may be partially to blame, and will continue for millennia.
Barrier Islands support local economies, residents, tourism, fragile environments, and sometimes valuable resources. Yet, they are extremely susceptible to storms and sea level change. A new study examines the past 12,000 years in sediments to try to understand how these coastal landforms may be affected in the future.
