Methodology\\u00a0is explained in\\u00a0[Lindo-Atichati et al.
As a brief summary, we constructed a hierarchy of four ocean-atmosphere models
operating at multiple scales within a 1 \\u00d7 1 deg domain of the Belizean
Barrier Reef. The four models are: 1) A Low-resolution Ocean model and Low-
resolution Atmospheric model (LOLA); (2) A High-resolution Ocean model and
Low-resolution Atmospheric model (HOLA); (3) A High-resolution Ocean model and
High-resolution Atmospheric model (HOHA); (4) A High-resolution Ocean model
and High-resolution Atmospheric model with Tidal forcing (HOHAT). The ocean
models are based on the HYbrid Coordinate Ocean Model (HYCOM, Bleck, 2002;
Chassignet et al., 2003; Wallcraft et al., 2009). The atmospheric models are
based on the non-hydrostatic Weather Research and Forecasting (WRF) and on the
Navy Operational Global Atmospheric Prediction System (NOGAPS). The drifter
data was from surface drifters provided by the Consortium for Advanced
Research on Transport of Hydrocarbon in the Environment
Sampling and analytical procedures:
From May 30 to July 2 of 2013, 55 drifter deployments were made at 1\\u20135 km
off a 40 km stretch of the BBR centered on South Water Caye (16.82 deg N,
87.97 deg W) (Fig. 2 b and c of\\u00a0[Lindo-Atichati et al
The hierarchy of four ocean-atmosphere models were used for the larger area
from 16.35 to 17.30 deg N, and from 87.48 to 88.47 deg W (Fig. 1 of\\u00a0
[Lindo-Atichati et al
The drifters are drogued at 40 cm and designed to sample the near-surface
current while minimizing windage. They are tracked using Global Positioning
System (GPS) every second with 5 m accuracy. The GT-31 GPS receivers are set
in a waterproof housing attached to the drifter.";

"Understanding the patterns, causes and consequences of larval dispersal is a major goal of 21st century marine ecology. Patterns of dispersal determine the rates of larval exchange, or connectivity, between populations. Both physical factors (e.g., water movement) and biological factors (e.g., larval behavior) cause variation in population connectivity. Population connectivity, in turn, has major consequences for all aspects of an organism's biology, from individual behavior to metapopulation dynamics, and from evolution within metapopulations to the origin and extinction of species. Further, understanding population connectivity is critical for the design of effective networks of marine reserves, creation of vital tools in conservation, and the development of sustainable fisheries.
Over the last decade, three methods, each of which tells something slightly different, have emerged as leading contenders to provide the greatest insights into population connectivity. First, coupled biophysical models make assumptions regarding water flow, larval behavior and ecology, to predict population connectivity. Second, indirect genetic methods use spatial distributions of allele frequencies to infer population connectivity. Third, direct genetic methods use parentage analyses, tracing recruits to specific adults, to measure population connectivity. Despite advances, lack of integration means that we do not know the predictive skill of biophysical models, or the extent to which patterns of dispersal predict spatial genetic structure. The overall objective of this proposal is to conduct an integrated investigation of population connectivity, using all three methods in one tractable system: the neon goby, Elacatinus lori, on the Belizean Barrier Reef. There are three motives for this choice of study system: i) fourteen highly polymorphic microsatellite loci have been developed, facilitating the assignment of recruits to parents using parentage analyses and the measurement of dispersal; ii) the physical oceanography of the Belizean Barrier Reef is well-studied, facilitating the development and testing of coupled biophysical models; and, iii) E. lori has a relatively small biogeographic range, facilitating analysis of the spatial distribution of allele frequencies throughout its range.
Broader Impacts. The grant will support one postdoc and two graduate students who will be trained in scientific diving, marine fieldwork, population genetics, biophysical modeling, and mathematical modeling, and will gain collaborative research experience. PIs will incorporate research findings in their courses, which cover all these topics. The grant will also broaden participation of under-represented groups by supporting six undergraduates from groups traditionally underrepresented in STEM fields. In each year of the project there will be an All Participants meeting to reinforce the network of participants. A project website will be developed, in English and Spanish, on the theme of larval dispersal and population connectivity. This will include a resource for K-12 marine science educators developed in collaboration with a marine science educator. All PIs will ensure that results are broadly disseminated to the scientific community and general public via appropriate forms of media.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
For example,
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
