Estimated abundances of cetacean species in the Northeast Atlantic from two multiyear surveys conducted by Norwegian vessels between 2002-2013
(Peer reviewed; Journal article, 2020)Two shipboard line-transect surveys of the Northeast Atlantic were conducted between 2002–2007 and 2008–2013 to meet the ongoing requirements of the Revised Management Procedure (RMP) for common minke whales (Balaenoptera ... -
Estimating and mitigating post-release mortality of European eel by combining citizen science with a catch-and-release angling experiment
(Journal article; Peer reviewed, 2018)Several anguillid eel species have experienced severe population declines over the past decades, particularly the European eel (Anguilla anguilla), which is listed as critically endangered by the International Union for ... -
Estimating catch-at-age by combining data from different sources
(Journal article; Peer reviewed, 2005)Estimating the catch-at-age of commercial fish species is an important part of the quota-setting process for many different species and almost all countries with a fishing fleet. Current procedures are usually very ... -
Estimating cod egg developmental stage based on DNA concentration
(Journal article; Peer reviewed, 2017)Pelagic egg surveys are commonly used to map Atlantic cod spawning areas in the northeastern Atlantic. However, a sampling location may not necessarily indicate a spawning location, because more developed eggs may have ... -
Estimating g(0) from single observer data
(Journal article; Peer reviewed, 2010-06)In this paper we estimate g(0), or equivalently the effective strip half-width, using data from a line transect survey which has been operated in double observer mode only a small fraction of the time. By letting the ... -
Estimating tail-beat frequency using split-beam echosounders
(Journal article; Peer reviewed, 2009-02-04)Data from a standard split-beam echosounder are used to estimate tail-beat frequency within a dense herring (Clupea harengus L.) layer. The data were collected by lowering a horizontally projecting 38 kHz split-beam ... -
Estimating target strength and physical characteristics of gas-bearing mesopelagic fish from wideband in situ echoes using a viscous-elastic scattering model
(Peer reviewed; Journal article, 2021)Wideband (38 and 50–260 kHz) target strength of organisms were measured in situ using a towed platform in mesopelagic (200–1000 m depth) layers. Organisms with a gas-inclusion are strong scatterers of sound and acoustically ... -
Estimating the spatial distribution of vocalizing animals from ambient sound spectra using widely spaced recorder arrays and inverse modelling
(Journal article; Peer reviewed, 2019)The sound energy from marine mammal populations vocalizing over extended periods of time adds up to quasi-continuous “choruses,” which create characteristic peaks in marine sound spectra. An approach to estimate animal ... -
Estimating the temporal overlap between post-smolt migration of Atlantic salmon and salmon lice infestation pressure from fish farms

Estimation and classification of temporal trends to support integrated ecosystem assessment
(Peer reviewed; Journal article, 2020)We propose a trend estimation and classification (TREC) approach to estimating dominant common trends among multivariate time series observations. Our methods are based on two statistical procedures that includes trend ... -
Estimation of annual mortality rates for eastern oysters (Crassostrea virginica) in Chesapeake Bay based on box counts and application of those rates for projection of population growth of both C. virginica and the Asian oyster (C. ariakensis)
(Journal article; Peer reviewed, 2008-08)In an effort to restore the ecological role of oysters in Chesapeake Bay and the economic benefits of a commercial fishery, the states of Maryland and Virginia are considering introducing the nonnative Asian oyster ... -

Estimation of Pup Production of Hooded and Harp Seals in the Greenland Sea in 2007: Reducing Uncertainty Using Generalized Additive Models
(Journal article; Peer reviewed, 2010-02-11)The pup production of the Greenland Sea populations of hooded and harp seals were assessed in aerial surveys using two aircrafts for reconnaissance flights and photographic surveys along transects over the whelping areas ... -
Estimation of the parameters of fish stock dynamics from catch-at-age data and indices of abundance: can natural and fishing mortality be separated?
(Journal article; Peer reviewed, 2007)Models for fluctuations in size of fish stocks must include parameters that describe expected dynamics, as well as stochastic influences. In addition, reliable population projections also require assessments about the ... -

Ethics of assisted evolution in marine conservation
(Peer reviewed; Journal article, 2019)Climate change is outpacing existing rates of evolution and adaptation for many marine organisms. Human societies are pushing hard to find new solutions to save and protect marine ecosystems, generating research on ... -

Eutrophication and algal growth in the North Sea. In: Symposium Mediterranean Seas 2000
(Conference object, 1993)The North Sea is a shallow shelf sea with an area of 0.6 million km^2, surrounded by densely populated land areas. The general water circulation is counter-clockwise, and an annua1 freshwater input of 400 km^3 results ...
