Input and cycling of iron in the Gulf of Aqaba, Red Sea
[1] The Gulf of Aqaba, northern Red Sea, is an ideal natural laboratory for studying the impact of atmospheric dry deposition of iron to the ocean surface. We have measured atmospheric iron deposition weekly for 18 months, and dissolved and total dissolvable iron concentrations in the stratified summer (August) and well-mixed winter (March) water column. Concentrations of dissolved and total di...
متن کاملSources and fluxes of atmospheric trace elements to the Gulf of Aqaba, Red Sea
[1] We present the first comprehensive investigation of the concentrations, fluxes and sources of aerosol trace elements over the Gulf of Aqaba. We found that the mean atmospheric concentrations of crustally derived elements such as Al, Fe and Mn (1081, 683, and 16.7 ng m ) are about 2–3 times higher than those reported for the neighboring Mediterranean area. This is indicative of the dominance...
متن کاملStatus of trace metals in surface seawater of the Gulf of Aqaba, Saudi Arabia.
The Gulf of Aqaba (GoA) is of significant ecological value with unique ecosystems that host one of the most diverse coral communities in the world. However, these marine environments and biodiversity have been threatened by growing human activities. We investigated the levels and distributions of trace metals in surface seawater across the eastern coast of the Saudi GoA. Zn, Cu, Fe, B and Se in...
متن کاملAtmospheric aerosols alter oceanic activity
Atmospheric aerosols alter oceanic activity Oceans remain a key convergence point where anthropogenic and natural environmental effects can affect climate change and alter food chains. For example, mineral dust, soot, organic molecules, and other microscopic particles can become aerosolized in the atmosphere and provide nutrients and trace metals for phytoplankton in the open ocean.

متن کاملComparison between pure-water- and seawater-soluble nutrient concentrations of aerosols from the Gulf of Aqaba
Seawater-soluble nutrient fractions of aerosols better represent the contribution of aerosol dry deposition to the nutrient load from this source to the ocean than any estimates based on aerosol nutrients leached in pure water or acidic solutions. To understand the solubility difference between seawater and pure water, 31 pairs of aerosol samples collected from the Gulf of Aqaba were extracted ...
