Ocean acidification of the North Pacific Ocean
The addition of fossil fuel carbon dioxide to the atmosphere is rapidly changing seawater chemistry and the calcium carbonate saturation state of the world’s oceans as a result of the acidifying effects of CO2 on seawater. This acidification makes it more difficult for many marine organisms (e.g., corals, plankton, calcareous algae, and mollusks) to build skeletons, tests, and shells of calcium...
متن کاملMode coherence at megameter ranges in the North Pacific Ocean
This article analyzes the coherence of low-mode signals at ranges of 3515 and 5171 km using data from the Acoustic Thermometry of Ocean Climate ~ATOC! and Alternate Source Test ~AST! experiments. Vertical line arrays at Hawaii and Kiritimati received M-sequences transmitted from two sources: the 75-Hz bottom-mounted ATOC source on Pioneer Seamount and the near-axial dual-frequency ~28/84 Hz! AS...
متن کاملRelationship between depth and age in the North Pacific Ocean
[1] The North Pacific contains active mid-oceanic ridges and the oldest, Jurassic (166.8 ± 4 Ma), drilled oceanic crust. Its bathymetry is therefore critical to studies of the applicability of thermal contraction models (e.g., the infinite half-space and cooling plate) to the subsidence of seafloor with crustal age. The bathymetry, however, contains seamounts and oceanic islands (e.g., Mid-Paci...
متن کاملA decade of acoustic thermometry in the North Pacific Ocean
[1] Over the decade 1996–2006, acoustic sources located off central California (1996– 1999) and north of Kauai (1997–1999, 2002–2006) transmitted to receivers distributed throughout the northeast and north central Pacific. The acoustic travel times are inherently spatially integrating, which suppresses mesoscale variability and provides a precise measure of ray-averaged temperature. Daily avera...
متن کاملWind-Driven Variability of the Subtropical North Pacific Ocean
The Argo array provides a unique dataset to explore variability of the subsurface ocean interior. This study considers the subtropical North Pacific Ocean during the period from 2004 to 2011, when Argo coverage has been relatively complete in time and space. Two distinct patterns of Argo dynamic height transport function (d DH) are observed: in 2004/05, the gyre is stronger, and in 2008/09 it i...
