Accounting for marine economic activities in large marine ecosystems
We develop an index that is a measure of the intensity of marine activities in large marine ecosystems (LMEs). We compare this marine activity index with an index of socioeconomic development across ocean regions. This ...
Reconciling end-to-end and population concepts for marine ecosystems
The inherent complexities in the structure and dynamics of marine food webs have led to two major simplifying concepts, a species-centric approach focused on physical processes driving the population dynamics of single ...
Estimating the economic benefits of regional ocean observing systems
(Woods Hole Oceanographic Institution, 2005-04)
We develop a methodology to estimate the potential economic benefits from new investments in regional coastal ocean observing systems in US waters, and apply this methodology to generate preliminary estimates of such ...
Deep-sea mining of seafloor massive sulfides
The potential emergence of an ocean mining industry to exploit seafloor massive sulfides could present opportunities for oceanographic science to facilitate seafloor mineral development in ways that lessen environmental harms.
Ocean acidification’s potential to alter global marine ecosystem services
(Oceanography Society, 2009-12)
Ocean acidification lowers the oceanic saturation states of carbonate minerals and decreases the calcification rates of some marine organisms that provide a range of ecosystem services such as wild fishery and aquaculture ...
Why compare marine ecosystems?
(Oxford University Press, 2009-08-30)
Effective marine ecosystem-based management (EBM) requires understanding the key processes and relationships controlling the aspects of biodiversity, productivity, and resilience to perturbations. Unfortunately, the scales, ...
A potential bias in coral reconstruction of sea surface temperature
(American Geophysical Union, 2004-03-25)
Isotopic measurements in corals are used to reconstruct past sea surface temperature. These reconstructions are based on calibration regression analyses using paired measurements of modern isotopic composition and sea ...
On non-stationarity of ENSO
(American Geophysical Union, 2003-09-13)
Evolutionary spectral analysis has been used to study changes through time in the variability of ENSO-related time series. However, the significance of estimated evolutionary spectra has not been formally assessed. This ...
A nonparametric test for change in variability using a proxy record with an application to ENSO
(American Geophysical Union, 2008-10-09)
A common problem in climate science is determining whether the pattern of variability in a particular process or variable has changed over time. When the modern observational record is short, this problem can be addressed ...
On estimating the number of species from the discovery record
(Royal Society, 2005-02-04)
A common approach to estimating the number of species in a taxonomic or other group is to extrapolate the temporal pattern of historical species discoveries or descriptions. A formal statistical approach to this problem ...
