摘要: The hydrothermal mats, mounds and chimneys of the southern Guaymas Basin are surface expression complex subsurface circulation patterns. In this overview we document most frequently visited features area with photographs, temperature measurements, selected geochemical data; many these distinct habitats await characterization their microbial communities activities. Microprofiler deployments on mats sediments show steep thermal gradients at millimeter-scale vertical resolution. Mapping sampling locations within suggest linkages to underlying shallow sills heatflow gradients. Recognizing inherent spatial limitations much current calls for a wider survey entire spreading region.
