Sentences with phrase «deposition by dust»

For the current climate, we calculate the reduction in wet deposition by dust radiative forcing and find that the aerosol burden is increased only modestly.

Not exact matches

Glaser et al. show that dust deposition mediated by frequent tropical storms was an important source of nutrients for the Everglades until about 2800 years ago, when a climatic shift in the tropical Atlantic and Gulf of Mexico led to weather patterns that sharply decreased the level of dust inputs and led to a drier climate and a gradual loss of soil phosphorus, carbon, and nitrogen.

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

«Recently, the deposition rates have been boosted by the resuspension of radionuclides in deposited particles, the 239,240 Pu content of which may originate from dusts from the East Asian continent deserts and arid areas.

The onsets of both abrupt Greenland warmings are slightly preceded by decreasing Greenland dust deposition, reflecting wetting of Asian deserts.

They showed the evidence to 77 domain experts (i.e., atmospheric chemists with expertise in condensation trails, and geochemists working on atmospheric deposition of dust and pollution), and asked about each of the claims made by «SLAP theorists.»

Here we took a different approach by seeking and applying dust deposition observations from hotspots for dust radiative and iron fertilization forcing: NH subtropical latitudes and the Southern Ocean.

Deposition of mineral dust plays an important role in the biogeochemical cycle of the oceans, by providing the nutrient iron, which affects ocean biogeochemistry with feedbacks to climate and dust production (Jickells et al., 2005; Section 7.3.4.4).

The input of trace elements by dust deposition is also of importance to terrestrial ecosystems.

2) That Planktos will be mitigating that shortfall by replenishing marine iron micronutrients in concentrations similar to dust storm deposition is also a fact.
