The words “coral reefs” conjure up images of a tropical paradise: shallow, warm, aquamarine waters, bright sunlight, white coral sand, and colorful, darting fish. But corals also live deep in the sea, in regions where the sun doesn’t penetrate and water temperatures remain just above freezing.
Bioluminescence is ubiquitous in the oceans, and especially prevalent in coastal regions where nutrients are abundant and life thrives. Yet scientists have little basic understanding of how bioluminescence is influenced by water temperatures, depths, seasons, geographic locations, even different times of day.
People have always fished. But the history of fishing is also the history of overfishing. For hundreds of years, the establishment and enforcement of fishery management policies have generated controversy, as competing authorities have searched for a way to balance competing goals—to catch as many fish as possible while conserving the resource. To resolve this dilemma, we have applied mathematics—and we are finding that the ancient solution may still prove effective in modern times.
Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse
both biologically and physically. The diversity and the high
energy of the ecosystem make estuaries remarkably resilient.
With a better understanding of these systems, we can reverse
their decline and restore the ecological richness of these
valuable, albeit muddy, environments.
The childhood of a barnacle is fraught with challenges. It hatches in shallow waters close to shore as a tiny larva, no bigger than a speck of dust. Currents sweep it to deeper, choppy waters, sometimes miles offshore. In these proving grounds each larva floats, at the mercy of hungry fish and swift ocean currents. Billions of larvae?including fish, lobsters, clams, starfish, and sea cucumbers?begin life this way. Only a few survive and return to shore, where they settle on rocks or sandy seafloor to become adults. Why larvae make their offshore journey remains unclear, but we are beginning to uncover the intricacies of their return trip?learning how waves, currents, eddies, tides, and other phenomena bring larvae back toward the shore.
