Nonmethane hydrocarbons (NMHCs) are emitted into the atmosphere from the ocean's surface. Although the oceanic contribution to the global NMHC budget is considered minor relative to other sources, it is one of the least well measured or understood. T

Background and Objective The size (0.5–1.0 cm) of early nonpalpable breast tumors currently detected by mammography and confirmed by stereotactic core biopsy is of the order of the penetration depth of near infrared photons in breast tissue. In pri

Stable oxygen isotopic analyses of scleractinian coral skeletons from the Gulf of Guinea in the eastern Atlantic reveal that the corals from this region can be used to identify periods of severe drought and above average precipitation in sub-Sahara A

Background: This investigation describes the preclinical development of a laser fiberoptic interstitial delivery system for the thermal destruction of small breast cancers. We propose adaptation of this technology to stereotactic mammographic instrum

Photokinetic studies demonstrate that sulfide is consumed in seawater upon light exposure. The half-life (t1/2) of sulfide (10 μM) added to Biscayne Bay water and Gulf Stream water are 49(±15) and 147(±10) min, respectively. Both UV and visible ra

Concurrent measurements of isoprene (2-methyl-1,3-butadiene) in seawater together with atmospheric concentrations in the Gulf Stream off the Florida coast were made. Florida Straits surface water concentrations of isoprene varied between 9.8 and 50.8
