The geological record of ocean acidification.
Ocean acidification may have severe consequences for marine ecosystems; however, assessing its future impact is difficult because laboratory experiments and field observations are limited by their reduced ecologic complexity and sample period, respectively. In contrast, the geological record contains long-term evidence for a variety of global environmental perturbations, including ocean acidifi...
متن کاملMetamorphic patterns in orogenic systems and the geological record
Regional metamorphism occurs in plate boundary zones. Accretionary orogenic systems form at subduction boundaries in the absence of continent collision, whereas collisional orogenic systems form where ocean basins close and subduction steps back and flips (arc collisions), simply steps back and continues with the same polarity (block and terrane collisions) or ultimately ceases (continental col...
متن کاملFirst record of the Indo-Pacific slender ponyfish Equulites elongatus (Günther, 1874) (Perciformes: Leiognathidae) from Turkey
Eight specimens of the slender ponyfish Equulites elongatus were collected, by otter trawl, between 6 December 2014 and 18 April 2015 from Turkish waters, off Mersin. This constitutes the second record of this species in the Mediterranean Sea and is about 530 km distant from the site of first record (Tel Aviv, Israel).
متن کاملOn the size distribution of sunspot groups in the Greenwich sunspot record 1874 - 1976
We investigate the size distribution of the maximum areas and the instantaneous distribution of areas of sunspot groups using the Greenwich sunspot group record spanning the interval 1874-1976. Both distributions are found to be well described by log-normal functions. Using a simple model we can transform the maximum area distribution into the instantaneous area distribution if the sunspot area...
متن کاملDo microplates in subduction zones leave a geological record
Active microplate boundaries in ocean-continent subduction zones may induce deformation of the overlying plate and spatial or geochemical variations in the volcanic arc. We discuss two modern cases. The first is the South Gorda-Juan de Fuca plate boundary in the Cascadia subduction zone, where there is little or no effect on the overriding plate and the oceanic plate takes up much of the deform...
