Sediment distribution on a storm-dominated insular shelf, Luquillo, Puerto Rico, U.S.A. Sediment distribution on a storm-dominated insular shelf, Luquillo, Puerto Rico, U.S.A.
A sea-floor mapping investigation designed to assess the sediment distribution, the movement of the nearshore sand supply, and the fate of sediment eroded from the shoreline was conducted using high-resolution sidescan-sonar, seismic reflection, and sediment sampling techniques on the northern insular shelf of Puerto Rico, off the town of Luquillo. Sea-floor structures and the...

AMS radiocarbon analyses from Lake Baikal, Siberia: Challenges of dating sediments from a large, oligotrophic lake AMS radiocarbon analyses from Lake Baikal, Siberia: Challenges of dating sediments from a large, oligotrophic lake
A suite of 146 new accelerator-mass spectrometer (AMS) radiocarbon ages provides the first reliable chronology for late Quaternary sediments in Lake Baikal. In this large, highly oligotrophic lake, biogenic and authigenic carbonate are absent, and plant macrofossils are extremely rare. Total organic carbon is therefore the primary material available for dating. Several problems are...

Linkages between chemical contaminants and tumors benthic Great Lakes fish Linkages between chemical contaminants and tumors benthic Great Lakes fish
Cutaneous papilloma have been observed at high prevalences in populations of brown bullheads (Ameiurus nebulosus) and white suckers (Catostomus commersoni) distributed throughout the Great Lakes, with no clear-cut delineation between prevalences in fish populations from industrialized sites in comparison to more pristine sites. However, bullhead papilloma prevalences greater than 20%...

A precise vertical network: Establishing new orthometric heights with static surveys in Florida tidal marshes A precise vertical network: Establishing new orthometric heights with static surveys in Florida tidal marshes
Elevation differences on the order of 10 cm within Florida's marsh system influence major variations in tidal flooding and in the associated plant communities. This low elevation gradient combined with sea level fluctuation of 5-to-10 cm over decadel and longer periods can generate significant alteration and erosion of marsh habitats along the Gulf Coast. Knowledge of precise and...

Structural outer rim of Chesapeake Bay impact crater: Seismic and bore hole evidence Structural outer rim of Chesapeake Bay impact crater: Seismic and bore hole evidence
Nine seismic-reflection profiles and four continuous core holes define the gross structural and stratigraphic framework of the outer rim of the Chesapeake Bay impact crater. The rim is manifested as a 90 km diameter ring of terraced normal-fault blocks, which forms a ∼320 m–1200 m high rim escarpment. The top of the rim escarpment is covered by a 20 m–30 m thick ejecta blanket. The...

Seasonal habitat use by brook trout, Salvelinus fontinalis (Mitchill), in a second-order stream Seasonal habitat use by brook trout, Salvelinus fontinalis (Mitchill), in a second-order stream
Seasonal habitat use by over-yearling and under-yearling brook trout, Salvelinus fontinalis (Mitchill), was examined in a second-order stream in north-central Pennsylvania, USA. The habitat occupied by brook trout and available habitat were determined in a 0.5-km stream reach during the spring, summer and autumn of 1989 and the spring and summer of 1990. Cover, depth, substrate and...

The proper name of the neotropical tree boa often referred to as Corallus enhydris (Serpentes: Boidae) The proper name of the neotropical tree boa often referred to as Corallus enhydris (Serpentes: Boidae)
Confusion regarding the application of the proper scientific name for the common Neotropical tree boa has existed since Linnaeus described Boa enydris and Boa hortulana in 1758. We review the nomenclatural history of the species and point out the misapplication of scientific names that have characterized this form. Our review indicates that the proper scientific name for this highly...
