    A common loon is released after biologists have taken blood samples for mercury analysis and have banded the bird. The banding of loons provides a reliable field method to re-observe individuals over many years and to track whether or not they are returning to their breeding lakes each summer. Additionally, banded loons are occasionally encountered alive or deceased on their non-breeding areas. A recovered banded loon provides important information on that individual’s or possibly, an entire breeding population’s wintering range. La Mauricie national park. Quebec. Canada

    Tara Oceans Expeditions - May 2011. l: Sophie Marinesque; r: Dr. Stéphane PESANT, specialist for plancton ecology, scientific coordinator on TARA; l: r: Dr. Stéphane PESANT, spécialiste de l'écologie du plancton, coordinateur scientifique sur TARA. Pyrosomes, or pyrosoma, are free-floating colonial tunicates that live usually in the upper layers of the open ocean in warm seas, although some may be found to great depth. Pyrosomes are cylindrical or conical shaped colonies made up of hundreds to thousands of individuals, known as zooids. Colonies range in size from less than one centimeter to several meters in length. Each zooid is only a few millimeters in size, but is embedded in a common gelatinous tunic that joins all of the individuals. Each zooid opens both to the inside and outside of the "tube", drawing in ocean water from the outside to its internal filtering mesh called the branchial basket, extracting the microscopic plant cells on which it feeds, and then expelling the filtered water to the inside of the cylinder of the colony. The colony is bumpy on the outside, each bump representing a single zooid, but nearly smooth, though perforated with holes for each zooid, on the inside. Pyrosomes are planktonic, which means that their movements are largely controlled by currents, tides and waves in the oceans. On a smaller scale, however, each colony can move itself slowly by the process of jet propulsion, created by the coordinated beating of cilia in the branchial baskets of all the zooids, which also create feeding currents. Pyrosomes are brightly bioluminescent, flashing a pale blue-green light that can be seen for many tens of meters. The name Pyrosoma comes from the Greek (pyro = "fire", soma = "body"). Pyrosomes are closely related to salps, and are sometimes called "fire salps." Sailors on the ocean are occasionally treated to calm seas containing many pyrosomes, all bioluminescencing on a dark night. Galapagos
