Frequently-anticipated questions:

What does this data set describe?

Title: Data from Playa de Luquillo, Puerto Rico Cruise JENA 1-91, 1991
Abstract:
The shallow marine shelf surrounding the Commonwealth of Puerto Rico has an area of about 3,500 km2 within the 200 m isobath, or nearly two-thirds that of the land area of the island. Deposits of sand and gravel on the insular shelf are of major importance to Puerto Rico because of their potential for low-cost development and because suitable onshore sources have been depleted. On an island where more than 85 percent of the population lives within 7 km of the sea and is dependent on the tourism that its beaches attract, it is necessary that scientific data related to oceanographic processes acting in the coastal zone and on the insular shelf be available to help formulate public policy regarding residential and commercial development along the coast, beach replenishment, and future utilization of marine resources.

How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    (process 1 of 1)
    Digital data were checked, formatted to dbSEABED input format, then processed using dbSEABED software to produce a range of output formats. The processing contained quality checking that may have declined to pass faulty or suspect data to outputs.
