Akashiwo sanguinea featured in the picture is a dinoflagellate, which is a type of phytoplankton that typically produces high concentrations of MAAs. Image taken by Françoise Morison using Flowcam® imaging.

Sunscreen for marine microbes

Humans are not the only species that apply suntan lotion to prevent sunburns. Microbes all over the globe produce their own suntan lotion, called MAAs, to protect themselves from the sun’s harmful rays.

The Christmas tree coral (Antipathes dendrochristos). In situ red and white color variants of Christmas tree coral colonies within the Southern California Bight. These coral colonies were found at 300 m depth and were approximately 50 cm tall (Fig. 1; Huff et al. 2013).

A unique, underwater niche for Christmas trees

Who would have thought that the Southern California Bight is a great place for Christmas trees to grow? Scientists have an inkling that a few key environmental factors influence underwater Christmas tree location and growth. Dr. David Huff and his research team are interested in accomplishing this via habitat modeling.

Gavia immer is the scientific name for the common loon, a top predator and a prominent symbol of the northern wilderness. Picture by Bob Weaver.

Top predators reveal the extent of mercury pollution in Canadian waters

Common loons, walleye, northern pike, and yellow perch play integral roles in ecosystem dynamics and environmental policy decisions. In this research project, they act as useful indicators to determine dangerously toxic levels of methylmercury in Canada.

Depth at marine bird observation sites within Glacier Bay grouped into 3 foraging classes.

Determining marine bird distribution in Glacier Bay, Alaska using fine spatial-scale hydrographic modeling

Researchers in Glacier Bay surveyed fifteen species of marine birds and linked the observations to instantaneous measurements of current speed and water surface elevation to determine how fine-scale tidal features influence bird distribution.
