... sea-level curves have focused on mangrove peat deposits, barrier ridges, and archaeological sites. However, in situ biological indicators provide the best evidence in support of varying sea-level positions during the late Holocene. The northeastern side of Key Biscayne, Florida, has two areas of rock...

...J EDWARD HOFFMEISTER; H GRAY MULTER Abstract A small rock reef, extending along the northeastern shore of Key Biscayne, Florida, for a distance of about 400 yards and seaward for 115 yards, has been found to be composed of a framework of fossilized mangrove roots belonging to the black mangrove...

... factor. Data that possess a relatively higher standard deviation, invariably at low frequency, will be unable to define relatively deep or thin layers. The shallow waters of Biscayne Bay near Key Biscayne, Florida served as the test sites for the marine MASW data acquisition ( Fig. 2 ). Key Biscayne...

...Harold R. Wanless Abstract Two distinct geometries of “lime” mud and sand bars (parallel with and transverse to topographic restriction) have formed in association with a linear bedrock ridge of Key Largo Limestone along the eastern (seaward) border of Biscayne Bay, Florida. On the south...

... was used to quantify biogenic macroporosity and permeability of the Biscayne aquifer, southeastern Florida. Biogenic macroporosity largely manifests as: (1) ichnogenic macroporosity primarily related to postdepositional burrowing activity by callianassid shrimp and fossilization of components...

With a graduate student, William Zucker, John went to Biscayne Bay to collect live larger foraminifers and to isolate...
