shout out for the sea – part three

Pacific Problems

First we basked with whales, then we explored the aquatic food chain, from the micro to the mouthwatering. In the final part of this mini-series on the state of the sea, let’s turn our gaze to the Pacific Ocean, where coral reefs are tumbling into oblivion, plastic is taking on the form of large land masses, and rampaging rubber duckies are on the loose. There’s some good news too.

Coral reefs are the oases of the oceans, the “rainforests of the sea,” sustaining a quarter of all marine species though they occupy less than 0.1 percent of the world’s watery surface. They are living structures formed by colonies of small creatures that exude calcium carbonate as an exoskeleton, creating masses that are underwater havens of life.

But they’re picky buggers, worse than that prima donna Goldilocks….

shout out for the sea – part two

Phytoplankton and Fisheries

Last time I wrote, we were out watching whales, the biggest creatures in the ocean. This time, let’s start small, with those phytoplankton that are the foundation of the marine food web, the organisms that make water so blue to our eyes. According to NASA’s Earth Observatory, phytoplankton serve as a “biological carbon pump” that transfers about 10 gigatonnes of carbon from the atmosphere to the deep ocean each year. They bloom and retreat. They move and wander through the ocean. They provide sustenance for everything from teeny tiny fish to the great whales I saw off Cape Cod.

shout out for the sea – part one

August 18, 2011 By Meera Leave a Comment

Last month I boarded a small ship in Cape Cod and headed out to sea in search of whales. The going was easy, the day pleasant, the seas calm. The voice of a naturalist wafted from the loudspeakers, filling our heads with biological facts and pointing out shearwaters as they skimmed above the surface of the water on lance-like wings. And the whales! We observed cetaceans of the filter-feeding mysticetes variety. Humpbacks rose from the water, just a hint of their immense size revealed with each surfacing, “carrying their tonnage / of barnacles and joy,” in the words of poet Mary Oliver. Three traveled together, each emergence and descent repeated in the same order…one, two, three. One minke whale penetrated the surface of the water just off the ship’s starboard side, and vanished a second later.

At any one moment, only a fraction of the leviathans were visible, but even with their immensity, the whales only represented an infinitesimal percentage of the abundance of life we witnessed that day. The color of the water revealed much of the rest. Water, alone, is colorless. Come winter I’ll crave the crystal-clear liquid that hugs the equator, warm and wet, as will the humpbacks that will travel there to calve. But those tropical waters are aquatic deserts where life hovers only around the oases of coral reefs, many of which are dying. Here in the North Atlantic, the deep blue-green waters teem with untold existence—carbon-sucking, oxygen-generating, bottom-of-the-food-chain, maybe-not-so-charismatic-but-unbelievably-important phytoplankton. Without these creatures, an entire web would unravel.

That day, we were in Stellwagen Bank National Marine Sanctuary, a federally protected marine habitat, but “protected” is a hugely ambiguous word….
