  • Mysteries in the Mud

    August 3, 2019  |  By Sarah Hardy

    I’ve been a scientist for a pretty long time now, and one of the things I’ve learned over the years is that the more you learn, the more you realize how little you actually know.

  • Marine Snow

    When you imagine the ocean, you might picture a tropical paradise like Hawaii with deep, clear blue waters – but most of the ocean doesn’t look like that at all! Those clear waters are actually a result of nutrient depletion that limits the growth of phytoplankton, the “plants” of the sea.

  • 10 Years in the Making

    July 31, 2019  |  By Travis Kolbe

    If you would have told me 10 years ago that I would be on a boat in the Gulf of Alaska, working with scientists in July, diving at over a mile deep - I would have said “YA, RIGHT… I WISH”. Well, wishes come true now and then.

  • Hold Your Breath!

    July 30, 2019  |  By Eric Collins

    Like plants on land, sunlight-powered phytoplankton in the sea produce oxygen as a byproduct of their photosynthetic metabolism. And, like animals on land, animals and other heterotrophs in the sea respire that oxygen by breathing.

  • A Rocky Start

    July 27, 2019  |  By Brittany Jones

    It’s 11 o’clock at night, the sea is calm, the sky is foggy, but a beautiful shade of deep blue. Donned with hardhats and lifejackets, two scientists hold tag lags securing the box corer as the bosun and marine science tech guide the yellow frame off the deck and out over the water. We pull off the tag lines and watch the corer sink into the depths of the ocean. It’s our first station and our first deployment of the box corer, a device that samples sediment from the deep ocean.

  • Goldilocks and the Three Bears Plankton

    July 26, 2019  |  By Eric Collins

    As the remotely operated vehicle Global Explorer sinks through the water column on its way to explore the Gulf of Alaska Seamounts, it passes through the sunlit zone where phytoplankton grow before heading into the inky darkness of the deep sea.

  • First Impressions

    July 26, 2019  |  By Kate Ariola

    At first the Sikuliaq seemed like a daunting vessel to be on, what with all the cranes and moving parts that can knock you overboard, especially for my first time every being on a boat this large.

  • A Buzz of Activity

    July 21, 2019  |  By Katrin Iken

    The beginning of a research cruise is like living in a beehive. A group of people, many of whom have not met before, meet together on a research vessel that many have not used before.
