attribute	NC_GLOBAL	acquisition_description	String	Larval fishes were collected at each station using a Multiple Opening Closing Net and Environmental Sensing System (MOCNESS, [https://www.whoi.edu/instruments/viewInstrument.do?id=10008](\\"https://www.whoi.edu/instruments/viewInstrument.do?id=10008\\")) with a 1m2 opening and 150um mesh nets (MOC1). To capture larval fishes and mesozooplankton on a fine horizontal spatial scale, we sequentially fired each MOCNESS net every ~120-150m. Traveling at a speed of 2 m s-1 each MOC1\u00a0net sampled ~120-150 m3. We fired a total of nine nets per tow. One net was open from the surface to depth (net zero), and eight nets sampled discrete depths. Net 0 was not enumerated for larval fish. Net 4 (or Net 5 in a few instances) did not have larval fish enumerated, as sample was collected for a collaborator. At every station, this fine-scale net sampling was repeated at 15m and 30m depth (randomized order). Once onboard, the nets were rinsed with seawater and the contents of each cod end immediately preserved in 95% ethanol. All larval fishes were separated out of the samples, enumerated, and stored for later SL measurements.\u00a0

attribute	NC_GLOBAL	instruments_0_description	String	The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton. All nets are black to reduce contrast with the background. A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release. A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).

attribute	NC_GLOBAL	projects_0_description	String	Description from NSF award abstract: The spatial pattern of organisms within pelagic marine environments is of significant ecological importance, and this is particularly true for larval fishes. Patchy prey and predator environments should lead to variation in predator-prey interactions, and thus to variations in larval fish growth and survival. These have proven very difficult to resolve in nature, due in large part to the broad range of spatial scales involved and technological challenges with adequately sampling the various processes simultaneously. This study will use new technology (In Situ Ichthyoplankton Imaging System - ISIIS) to simultaneously measure the fine-scale distribution of larval fishes in relation to their prey, their planktonic predators, and the physical environment of the Straits of Florida. This will be combined with targeted fine-scale net sampling and analyses of individual recent daily larval growth. By sampling a series of water masses at very high resolution, this study will address specific hypotheses concerning: i) the drivers of aggregations and patchiness, and ii) the biological consequences of predator-prey interactions at fine scales. The primary intellectual merit of the study is the unprecedented examination of plankton processes at scales of relevance to biological interactions among larval fishes, their prey, and their predators. This field study will further our understanding of the predator-prey interactions contributing to spatially explicit larval growth and mortality patterns. The focus on subtropical planktonic food webs will enhance scientific knowledge of these understudied pelagic ecosystems and provide valuable data for comparative analyses with pelagic food web dynamics at higher latitudes. A deeper understanding of pelagic planktonic ecosystems over a range of spatial and temporal scales is increasingly important as the oceans undergo major environmental changes. Substantial increases in the relative dominance of gelatinous organisms, for example, have the potential to cause major shifts in pelagic food webs. A better understanding of the fine-scale interactions of such food webs will help society anticipate and respond to the consequences of such changes. Note (07 Oct 2014): Funding for this project transferred from award OCE-1333800 to OCE-1419987, coincident with the Principal Investigator's affiliation change from University of Miami to Oregon State University.
