“…The same applies to the phosphorus concentrations in PW, which were similarly higher at the MSS than at the ICZ (about 3 times on average), which might be attributed to a high CaCO 3 content in the MSS sediments (80%, Rasheed et al, 2003). It has been long known that phosphate has a strong affinity for being adsorbed on reef carbonate sediments (Dekanel and Morse, 1978), and can also be trapped within the crystal lattice of carbonate granules (Rittenberg et al, 1955;Barrie et al, 1983;Balzer et al, 1985 andSugai, 1987).…”

“…This is best understood as NH 4 + being the first inorganic product in the regeneration of nitrogenous organic material by microorganisms. NO 2 -and NO 3 -are formed in sediment only under well-oxygenated conditions by nitrifying bacteria through the nitrification process (Rittenberg et al, 1955;Billen, 1975). Ammonium fluxes from both sites and for all stations tended to increase with increasing inorganic phosphate fluxes ( Fig.…”

SUMMARY: Measurements of dissolved inorganic nutrients (NH-2 and SiO 2 ) in pore waters (PW) and overlying bottom waters (OBW) were carried out in sediments of two reefs on the Jordanian coast of the Gulf of Aqaba at different water depths down to 30 m. One of the two sites was a marine reserve in front of the Marine Science Station (MSS) and the other hosted an Industrial Complex Zone (ICZ). The PW samples were retrieved using specially designed interstitial water traps. The concentrations in the OBW were within the typical range reported for oligotrophic tropical oceans. They showed minor variations with depth due to a well-mixed water column. Higher nutrient values were found at the ICZ compared to MSS suggested anthropogenic nutrient inputs. Our results showed significantly higher nutrient concentrations in the PW than in the OBW. The average concentrations in PW were about 16, 6, 9 and 5 times higher than the average values reported in the OBW for NH 4 + , NO 2 -+NO 3 -, HPO 4 -2 and SiO 2 respectively. Average fluxes of the dissolved inorganic nutrients were estimated in this study using the pore water gradient concentration across the sediment-water interface. Average diffusion fluxes were in the ranges 1. 41-46.44, 2.68-18.25, 0.04-0.60 and 9.68-16 , HPO 4 -2 and SiO 2 respectively. Flux of all nutrients was higher at the MSS. This can be attributed to higher sediment organic matter content and high biological activity. The results of this study demonstrate (i) the importance of coral reef sediments in recycling nutrients for coral reef communities and (ii) the effect of pumping cooling water on the nutrient regeneration process. -2 y SiO 2 ) del agua intersticial (PW) de sedimentos de dos arrecifes y de las capas del agua profundas (OBW). Uno de los dos lugares era una reserva marina en frente de la Marine Science Station (MSS) y el otro estaba enclavado en la zona de un complejo industrial (ICZ). Las muestras del PW se recogian utilizando unas trampas especiales diseñadas para aguas intersticiales. Las concentraciónes de nutrientes en la OBW estaban dentro del rango típico que se reporta para oceanos trópicales oligotróficos. Estas mostraban pequeñas variaciones con la profundidad debido a que la columna de agua estaba mezclada. Los valores mas elevados de nutrientes fueron hallados en la ICZ comparados con los de la MSS, lo que sugeria que los vertidos de nutrientes eran de origen antropogé-nico. Nuestros resultados mostraban concentraciones de nutrientes significativamente mas elevadas en las PW que en las OBW. Las concentraciones medias en la PW eran alrededor de 16, 6, 9 y 5 veces mas altas que el promedio de los valores alcanzados en las OBW para NH 4 + , NO 2 -+NO 3 -, HPO 4 -2 y SiO 2 respectivamente. El promedio del flujo de los nutrientes inorgánicos disueltos fueron estimados en este estudio utilizando un gradiente creciente de la concentración del agua intersticial a través de la interfase agua-sedimento. El promendio del flujo de difusión oscilaba entre 1. 41-46.44, 2.68-18.25, 0.04-0 -2 y ...

“…This is verified by the fact that the basin water is not stagnant and devoid of oxygen. In fact, Rittenberg, Emery, and Orr (1955) showed that about 3.0 ml of oxygen is required annually for oxidation of organic matter in the top 30 cm of a 1 sq cm column of sediment at the bottom of Santa Catalina Basin and about 1.5 ml is' needed for that of the Santa Barbara Basin. At these rates of use, all the oxygen in the basin waters would be used in only about 2 years; thus, there must be conlplete replenishment in less than 2 years to account for the' absence of appreciable depletion of oxygen in the basin waters as compared with those of the open sea at the same depths as the basin sills.…”

“…If so, then it is reasonable to expect that a colloidal phase may be present (Emery and Dietz, 1950) and available for deposition. Only the most sketchy chemical data were available for the computations and the situation is little better now, except that Rittenberg, Emery, and Orr (1955) have shown that the southern When the problem of the phosphorite off southern California was first studied (Dietz, Emery, and Shepard, 1942), the Miocene age of it was recognized to be strongly opposed by the wide distribution on the sea floor of large nodules, in contrast to their scarcity on the adjacent land and by the obvious in situ position of many of the nodules atop banks that must have been eroded in post-Miocene times. The post-Late Pliocene age was opposed by the frequency of pure Miocene faunas in the nodules, although it was favored by the Late Pliocene to Recent and mixed faunas in other nodules.…”

“…An examination of the distribution of nutrients in basin sediments and overlying waters was made by Rittenberg, Emery, and Orr (1955). Three basins were selected as representative of all basins: Santa Catalina because of its change from aerobic to anaerobic conditions at a depth of about 2 hematite near the sediment surface, siderite at intermediate depth, and pyrite nearer the bottoms of many cores.…”

The benthic oxygen demand and inorganic nutrient release have been investigated in the coastal zone of the Mid-Atlantic Bight of the United States using in situ and ship-board incubations t,o estimate fluxes across the sediment-water interface. Oxygen demand ranged from ca. 70 nil m-2 hr-1 nearshore in warm (25 "C) muddy sediments to ca. 4 ml m-? hr-1 in cold (6 "C), coarse-grained sediments offshore. Ammoniumionflux was out of the sediments in all but 4 of 29 incubations, while nitrate was often found to be utilized within or on t,he sediments, decreasing in 10 of 29 incubations. Those locations with fluxes of nitrate out of the sediment had concentrations in the pore water that were generally high, sometimes u p to several mM 1-*. Nitrate fluxes were always well below those of ammonia, even where high almost equivalent concentrations of both NH4 and NO:, were found a t the same locale.On George's Bank only 13 "/o of total N demand b y the phytoplankton was estimated to be supplied by the benthos, whereas in New York Bight the supply amounted to 42 "/o of the demand. This difference can be attributed t o higher pelagic biological and advective (mixing and upwelling) inputs to George's Bank compared to the relatively well stratified New York Bight in late summer and autumn.
