    String summary "Liquid Robotics Wave Glider, Honey Badger (G3), 2015, AIS. The MAGI mission is to use the Wave Glider to sample the late summer chlorophyll bloom that develops near 30°N, with the goal of using the camera and LISST-Holo to try to identify species in the blooms and then follow the development of phytoplankton aggregates. These aggregates have recently been shown to be a significant part of the total amount of carbon that sinks to the deep sea. Karl et al (2012) found that in each of the past 13 years, there was a flux of material to 4,000 m (the summer export pulse) that represented ~20% of the total annual flux. Work based on satellite ocean color data over the past decade has revealed the existence of large phytoplankton blooms in the Pacific Ocean that cover thousands of km2, persist for weeks or longer, and are often dominated by nitrogen-fixing diatom symbioses (Wilson et al. 2008). We hope to be able to examine whether this aggregation is occurring in the vast oceanic regions north and east of Hawai'i and provide a basin-scale context for the ALOHA observations. These events have proven difficult to study outside of the time series station ALOHA at Hawai'i.";

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{?query}
For example,,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
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.
