Trace metal cycling in the surface water of the South China Sea: Vertical fluxes, composition, and sources
Trace metal cycling the surface water the South China Sea: Vertical fluxes composition sources
2014/4/16
We deployed floating traps in the surface waters of the South China Sea on four occasions at depths of 30 m,100 m, and 160 m from 2006 to 2007 to quantify vertical metal fluxes in the surface water an...
Contrasting biogeochemistry of six trace metals during the rise and decay of a spring phytoplankton bloom in San Francisco Bay
biogeochemistry six trace metals during the rise decay of a spring phytoplankton bloom San Francisco Bay
2014/4/22
The spring 2003 phytoplankton bloom in South San Francisco Bay (South Bay) affected the cycling of Mn, Co, Zn, Ni, and Pb, but not Cu. We followed this diatom bloom for 2 months, capturing a peak in c...
Effects of dust deposition and river discharges on trace metal composition of Trichodesmium spp. in the tropical and subtropical North Atlantic Ocean
dust deposition river discharges trace metal composition Trichodesmium spp. tropical subtropical North Atlantic Ocean
2014/5/4
We present the elemental composition (Al, Cd, Co, Cu, Fe, Mn, Mo, Ni, V, Zn, and P) of field-collected Trichodesmium populations. To distinguish the effects of river discharges (Amazon and Niger River...
Natal trace-elemental signatures in the otoliths of an open-coast fish
Natal trace-elemental signatures otoliths open-coast fish
2014/5/13
We show that chemical differences found along the open coast are sufficiently strong to leave a readable natal signature in fish otoliths. Laser ablation inductively coupled plasma mass spectrometric ...
Spatial and temporal variation in trace elemental fingerprints of mytilid mussel shells: A precursor to invertebrate larval tracking
Spatial and temporal variation trace elemental fingerprints mytilus mussel shells invertebrate larval tracking
2014/5/8
Elements incorporated into developing hard parts of planktonic larvae record the environmental conditions experienced during growth. These chemical signatures, termed elemental fingerprints, potential...
Phosphorus and trace metal limitation of algae and bacteria in Lake Superior
Phosphorus and trace metal algae and bacteria Lake Superior
2014/5/14
We performed a set of nutrient-enrichment bioassay experiments using metal-clean protocols, testing for macronutrient and micronutrient limitation of algae and bacteria in western Lake Superior. Our a...
Assimilation and retention of selenium and other trace elements from crustacean food by juvenile striped bass (Morone saxatilis)
Assimilation and retention of selenium other trace elements crustacean food juvenile striped bass Morone saxatilis
2014/5/27
Estimates of the assimilation and retention of trace elements from food by fish are useful for linking toxicity with the biogeochemical cycling of these elements through aquatic food webs. Here we use...
Trace metal assimilation and release budget in Daphnia magna
Trace metal assimilation release budget Daphnia magna
2014/5/26
The assimilation efficiency (AE), efflux rate, and release budget of Cd, Cr(III), Se(IV), and Zn by a freshwater zooplankton Daphnia magna were measured under different food concentrations. The AEs of...
