Maximum dissolution rates of biogenic silica as a function of depth in the ocean were calculated as a function of the variables temperature, pH, dissolved silicon concentration, and the measured surface area of radiolarian skeletons of a single speci

The tests of planktonic foraminifera recovered from deep-sea sediment are commonly observed to encapsulate fine grain carbonate sediment within their chambers. In sediment below the lysocline, the interstitial water within the chambers may not be as

Published estimates regarding the amount of glacially eroded sediments produced by the Antarctic continent, and the amount of dissolution that this material undergoes once it reaches Antarctic waters, appear to be overestimated by several orders of m

The rate of solution of a single biogenic opal test is a function of solution temperature, degree of saturation, available surface area of the test and any coating or protective layer the test may have. Grazing has both adverse and beneficial effects

The solution rate of biogenic opal in near-surface sediments in the Central Equatorial Pacific is three to eight orders of magnitude lower than similar acid-cleaned samples. Iron, magnesium and calcium aluminosilicates may be the minerals which are f

The skeletons of phaeodarian Radiolaria transport and redistribute silica to the tropical deep oceans by dissolving in the water column and on the sea floor. The skeletons are initially solid but within a few days to months become progressively more
