Oceanic Meanderings

Myotome meanderings

The formation of muscles within the vertebrate embryo is a tightly orchestrated and complex undertaking. Beyond the initial specification of cells to become muscle are several complex cellular movements and migrations, which lead to the positioning of muscle precursors at specific locations within the embryo. The consequent differentiation, elongation and striation of these cells results in the...

Oceanic Protists

extraordinary species diversity and variety of interactions of protists in the sea are only now being fully appreciated. Figure 1 shows representative examples of marine protists, and of methods used to visualize these microbes. Protists can be autotrophic or heterotrophic. The former, also called microscopic algae, contain chloroplasts, thrive by photosynthesis, and are at the base of all ocea...

Oceanic methane biogeochemistry.

Measurements of dissolved methane in the ocean have been available for only about 50 years. Methane measurements in sediments, where concentrations are millimolar, were first reported in the mid-1950s, while measurements of methane in ocean waters, where concentrations are nanomolar, were first reported in the late 1960s. Methane is the most abundant hydrocarbon in the atmosphere, where it play...

Oceanic Double-diffusion: Introduction

Stereophotogrammetry of Oceanic Clouds

This study extends ground-based stereophotogrammetry of clouds to oceanic settings, where there are often none of the landmarks used in traditional camera calibration. This paper introduces a zero-landmark calibration technique and tests it with two off-the-shelf digital cameras situated about 1 km apart facing Biscayne Bay in Miami, Florida. The precision of the stereo reconstruction is studie...
