The use of coded microwire tags mark-recapture studies of juvenile Caribbean spiny lobster, Panulirus argus The use of coded microwire tags mark-recapture studies of juvenile Caribbean spiny lobster, Panulirus argus
To evaluate the suitability of using coded microwire tags (CWTs) to mark early-benthic-stage Caribbean spiny lobster, Panulirus argus, we compared the survival, growth, and feeding of tagged and untagged lobsters held in the laboratory through the first five juvenile molts. We also examined the growth of 65 microwire-tagged lobsters released into the wild as early-benthic-stage juveniles...

Water Resources Data Massachusetts and Rhode Island Water Year 1999 Water Resources Data Massachusetts and Rhode Island Water Year 1999
INTRODUCTION The Water Resources Division of the U.S. Geological Survey, in cooperation with State agencies, obtains a large amount of data pertaining to the water resources of Massachusetts and Rhode Island each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the States. To...

Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data
Water-resources data for the 1999 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 120 gaging stations and 69 partial-record sites; water levels at 187 observation wells and 26...

Trapping and migration of methane associated with the gas hydrate stability zone at the Blake Ridge Diapir: New insights from seismic data Trapping and migration of methane associated with the gas hydrate stability zone at the Blake Ridge Diapir: New insights from seismic data
The Blake Ridge Diapir is the southernmost of a line of salt diapirs along the Carolina trough. Diapirs cause faulting of the superjacent sediments, creating pathways for migration of fluids and gas to the seafloor. We analyzed reflection seismic data from the Blake Ridge Diapir, which is located in a region with known abundant gas hydrate occurrence. A striking feature in these data is...

Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay Time-averaged fluxes of lead and fallout radionuclides to sediments in Florida Bay
Recent, unmixed sediments from mud banks of central Florida Bay were dated using 210Pb/226Ra, and chronologies were verified by comparing sediment lead temporal records with Pb/Ca ratios in annual layers of coral (Montastrea annularis) located on the ocean side of the Florida Keys. Dates of sediment lead peaks (1978±2) accord with prior observations of a 6 year lag between the occurrence...

Photographic evaluation of the impacts of bottom fishing on benthic epifauna Photographic evaluation of the impacts of bottom fishing on benthic epifauna
The gravel sediment habitat on the northern edge of Georges Bank (East coast of North America) is an important nursery area for juvenile fish, and the site of a productive scallop fishery. During two cruises to this area in 1994 we made photographic transects at sites of varying depths that experience varying degrees of disturbance from otter trawling and scallop dredging. Differences...

Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon Post-Mazama (7 KA) faulting beneath Upper Klamath Lake, Oregon
High-resolution seismic-reflection profiles (3.5 kHz) show that a distinctive, widespread reflection occurs in the sediments beneath Upper Klamath Lake, Oregon. Coring reveals that this reflection is formed by Mazama tephra (MT), about 7 ka in age. The MT horizon is faulted in many places and locally displaced by as much as 3.1 m. Differential displacement of multiple horizons indicates...

The presence of high-affinity, low-capacity estradiol-17β binding in rainbow trout scale indicates a possible endocrine route for the regulation of scale resorption The presence of high-affinity, low-capacity estradiol-17β binding in rainbow trout scale indicates a possible endocrine route for the regulation of scale resorption
High-affinity, low-capacity estradiol-17β (E2) binding is present in rainbow trout scale. The Kd and Bmax of the scale E2 binding are similar to those of the liver E2 receptor (Kd is 1.6 ± 0.1 and 1.4 ± 0.1 nM, and Bmax is 9.1 ± 1.2 and 23.1 ± 2.2 fmol × mg protein-1, for scale and liver, respectively), but different from those of the high-affinity, low-capacity E2 binding in plasma (Kd...
