Population estimates of Pacific coast groundfishes from video transects and swept-area trawls

Oceanographic Literature Review, 1996
Demersal fish surveys are used for two purposes: to detect trends in multispecies communities for environmental assessment and to pro­ vide fishery independent stock assess­ ments for management. We compared remotely operated vehicle (ROV) and swept-area

Injection Rates - The Effect of Mobility Ratio, Area Swept, and Pattern

Society of Petroleum Engineers Journal, 1961
Abstract A method is presented for calculating approximate injection rates in secondary recovery operations. The method can he applied to cases of unequal fluid mobilities, irregular well patterns and boundary patterns. The steady-state pressure distributions for the four flood patterns reported by

Innovations in survey and sampling design in the Chilean Crustacean Swept Area Assessments

2012
No abstracts are to be cited without prior reference to the author.Three crustacean species are subject of yearly swept area assessments off Northern-Central Chile: a pandalid shrimp (Heterocarpus reedi) and two munidid squat lobsters (Cervimunida johni and Pleuroncodes monodon)

Correlations between Choriocapillaris Flow Deficits around Geographic Atrophy and Enlargement Rates Based on Swept-Source OCT Imaging

Ophthalmology Retina, 2019
Purpose: To determine the possible correlation between the annual enlargement rates (ERs) of geographic atrophy (GA) with the percentage and size of the choriocapillaris (CC) flow deficits (FDs) surrounding GA, measured with swept-source OCT angiography (

The effect of improved footrope contact measurements on trawl area swept estimates

Fisheries Research, 2004
Abstract Various net monitoring instruments have been used during the evolution of the Gulf of Alaska demersal trawl survey conducted by the Alaska Fisheries Science Center in an attempt to reduce haul-to-haul variability in estimates of relative density due to variation in trawl efficiency and swept area.

On Optimizing Search Efforts (Area Effectively Swept) Allocation in the Course of Search and Rescue Operations

2009
A solution is considered for a problem of optimal distribution of search efforts among areas while running search and rescue operations under limited search resources and probabilistic nature of a priori information about the location of an emergency object.

Quantifying Variability In Gear Performance On Ibts Surveys: Swept Area And Volume With Depth

2000
No abstracts are to be cited without prior reference to the author.The International Bottom Trawl Surveys (IBTS) on the western shelf represent an important source of fisheries independent data on the abundance and distribution of many important commercial species. Trawl hauls on these surveys are standardised to 30 minutes and four knots.

Design Charts for Estimating Swept Areas After Breakthrough in Flooding Heterogeneous Reservoirs

SPE Permian Basin Oil Recovery Conference, 1971
Abstract A study has been made and a series of charts are provided so that one may estimate the swept areas after breakthrough in flooding or cycling heterogeneous reservoirs. It is well known that reservoirs are not uniform and homogeneous, nor do they exist in uniform layers without crossflow, yet, the working ...
