Numerical model of frazil ice and suspended sediment concentrations and formation of sediment laden ice in the Kara Sea Numerical model of frazil ice and suspended sediment concentrations and formation of sediment laden ice in the Kara Sea
A one-dimensional (vertical) numerical model of currents, mixing, frazil ice concentration, and suspended sediment concentration has been developed and applied in the shallow southeastern Kara Sea. The objective of the calculations is to determine whether conditions suitable for turbid ice formation can occur during times of rapid cooling and wind- and wave-induced sediment resuspension...

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...

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...

Susceptibility of Arctic char to experimental challenge with Infectious Hematopoietic Necrosis Virus (IHNV) and Infectious Pancreatic Necrosis Virus (IPNV) Susceptibility of Arctic char to experimental challenge with Infectious Hematopoietic Necrosis Virus (IHNV) and Infectious Pancreatic Necrosis Virus (IPNV)
Arctic char Salvelinus alpinus were exposed to the fish pathogens infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV) to estimate susceptibility of the species to infection. Fish were immersion challenged at 46, 74, and 95 d posthatch for 5 h in viral concentration of 103 or 105 PFU(plaque-forming units)/mL and were monitored for 21 d...

Predicting the physical effects of relocating Boston's sewage outfall Predicting the physical effects of relocating Boston's sewage outfall
Boston is scheduled to cease discharge of sewage effluent in Boston Harbor in Spring 2000 and begin discharge at a site 14 km offshore in Massachusetts Bay in a water depth of about 30 m. The effects of this outfall relocation on effluent dilution, salinity and circulation are predicted with a three-dimensional hydrodynamic model. The simulations predict that the new bay outfall will...

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...

Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario
Managers often employ aerial survey information to manage waterfowl. Results of surveys by helicopter and from elevated platforms were compared to determine the accuracy of helicopters to detect waterfowl broods on beaver ponds in southern Ontario in 1996 and 1997. Fewer broods were detected from the helicopter than by observers in elevated platforms at wetland margins. When broods were

GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales
To construct forest landscape of pre-European settlement periods, we developed a GIS interpolation approach to convert witness tree records of the U.S. General Land Office (GLO) survey from point to polygon data, which better described continuously distributed vegetation. The witness tree records (1839-1866) were processed for a 3-million ha landscape in northern Wisconsin, U.S.A. at...
