Life Under Water in Monterey Bay
Lovell and Libby Langstroth, who wrote the text and took most of the stunning photographs for A Living Bay: The Underwater World of Monterey Bay (University of California, $60), have organized their book by the wide range of major habitats extending outward and downward from the shore. Sexual, chemical and predator-prey interactions are recurrent themes. Shown here (clockwise from lower left) are a leather star (Dermasterias imbricata) preying on Corynactis; Macrocystis kelp (the white spots on its blades are colonies of the encrusting bryozoan Membranipora membranacea); Pelagia ephyrae, which are tiny medusae (photograph by Freya Sommer); the aboral surface of a sea star (Asterina), showing its sieve plate (a buttonlike yellow structure that is the perforated opening of its water vascular system); and the "sand collar" that a female moon snail has molded about her shell from layers of mucus and sand to protect her fertilizaed eggs.

Happy Birthday to Alvin! August 2014 marks the 50th anniversary of Alvin, the submersible that has been so influential in ocean research, including the discovery of hydrothermal vents. In 2014, a retrofitted Alvin also took its first test cruise.
Heather Olins, a doctoral candidate at Harvard, studies microbial ecology at deep sea hydrothermal vents with the help of Alvin, and shares her personal tribute to the submersible on these landmark occasions.
