“…Correspondingly, differences appear in the circulation patterns at either side of MAR (Bower et al, 2002). These are reflected by different kinetic energy spectra of the current systems, indicating a rapidly evolving system west of MAR and a slow system east of MAR (Losee et al, 1989;LeTraon, 1991).…”

“…A surface-deep water link was shown by means of changes in potential vorticity along a meridional section at 30 W attributed to NAC and Azores Current coinciding with ARTICLE IN PRESS corresponding SST changes (Longhurst, 1998, p. 121). Kinetic energy spectra of the eastern North Atlantic indicate dominating periods >100 days and length-scales of 80-160 km (Losee, et al 1989;LeTraon, 1991), i.e. the range of mesoscale eddies (Colling, 2001, p. 73), which in turn determine surface chlorophyll distribution during vernal stratification (Longhurst, 1998, p. 121).…”

Pelagic fishes from depths of 250 to 3200 m from 45 N to 50 N were sampled during a mid-Atlantic cruise in 1982. These clustered into 6 assemblages, which were related to the Mid-Atlantic Ridge, the continental shelf edge and oceanic habitats. Spatial distribution of clusters coincided with SST and surface chlorophyll patterns. Cluster distribution further coincided with published mid-depth hydrography indicating that hydrographic recirculation features were an important determinant of community structure. Over the ridge, Melamphaidae, Serrivomeridae, Stomiidae and Centrolophidae increased in abundance. Horizontally, the myctophid Benthosema glaciale indicated the transition from temperate-subtropical to temperate-subarctic waters. The gadid Micromesistius poutassou and the alepocephalid Xenodermichthys copei were characteristic species for the shallow shelf edge assemblage. Vertically, extended depth ranges were stated for assemblages above MAR and the southern leg, as indicated for the species Gonostoma bathyphilum, and Schedophilus medusophagus. This was further tested for the saccopharyngid Saccopharynx ampullaceus. The increase of gelatinous plankton feeders over the ridge, in particular for S. medusophagus, is discussed with respect to a probable increase of gelatinous plankton abundance in the area considered. An error model was developed to address the contamination problem with respect to non-closing devices. r

“…Case et al (1993) and Alberte (1993) review the development of bathyphotometers and patterns of oceanic bioluminescence. Although developed in 1950s, one of the first large-scale applications of bathyphot ometers took place in late 1980s in North Atlantic to examine the differences in light production by various planktonic taxa (Batchelder and Swift, 1989;Losee et al, 1989;Batchelder et al, 1990Batchelder et al, , 1992Swift et al, 1995). These measurements are becoming more prevalent and have now been conducted off ships, on profiling and undulating systems, on moorings, and on autono mous underwater vehicles (AUVs; Widder et al, 1993;Moline et al, 2001Moline et al, , 2005Herren et al, 2005).…”

a b s t r a c tEcosystem function will in large part be determined by functional groups present in biological communities. The simplest distinction with respect to functional groups of an ecosystem is the differentiation between primary and secondary producers. A challenge thus far has been to examine these groups simultaneously with sufficient temporal and spatial resolution for observations to be relevant to the scales of change in coastal oceans. This study takes advantage of general differences in the bioluminescence flash kinetics between planktonic dinoflagellates and zooplankton to measure relative abundances of the two groups within the same-time space volume. This novel approach for distinguishing these general classifications using a single sensor is validated using fluorescence data and exclusion experiments. The approach is then applied to data collected from an autonomous underwater vehicle surveying 4500 km in Monterey Bay and San Luis Obispo Bay, CA during the summers of [2002][2003][2004]. The approach also reveals that identifying trophic interaction between the two planktonic communities may also be possible.

“…Considerable attention has been given to determine scales of biological and physical oceanographic processes and to identify the drivers of plankton patchiness. These questions have been addressed using a variety of different methods, including spectral analysis (Denman and Platt, 1976;Losee et al, 1989;Lovejoy et al, 2001;Washburn et al, 1998;Wiebe et al, 1996), autocorrelation or autocovariance functions (Chang et al, 2002;Mackas, 1984;Yu et al, 2002) correlograms or variograms (Dustan and Pinckney, 1989;Mackas, 1984;Yoder et al, 1987), wavelet analysis (Deutschman et al, 1993;Machu et al, 1999;Charria et al, 2003), and multifractal analysis (Seuront et al, 1996(Seuront et al, , 1999. Better understanding of the scales of variability can be used to help identify the physical and biological processes structuring biomass distribution and community structure, and help distinguish which processes are responsible at different scales (Chang et al, 2002;Cunningham et al, 2003;Dustan and Pinckney, 1989;Seliger et al, 1981).…”

Patchiness or spatial variability is ubiquitous in marine systems. With increasing anthropogenic impacts to coastal resources and coastal systems being disproportionately large contributors to ocean productivity, identifying the spatial scales of this patchiness, particularly in coastal waters, is of critical importance to understand coastal ecosystem dynamics. The current work focuses on fine scale structure in three coastal regions. More specifically, we utilize variogram analyses to identify sub-kilometer scales of variability in biological and physical parameters measured by an autonomous underwater vehicle (AUV) in the Mid-Atlantic Bight, Monterey Bay, and in San Luis Obispo Bay between 2001 and 2004. Critical scales of variability in density, turbidity, fluorescence, and bioluminescence are examined as a function of depth and distance offshore. Furthermore, the effects of undersampling are assessed using predictive error analysis. Results indicate the presence of scales of variability ranging from 10s to 100s of meters and provide valuable insight for sampling design and resource allocation for future studies.
