The density of sperm in the water column during the broadcast spawning events of marine invertebrates is often undetermined or reported in terms of fertilization potential. The density of sperm during such events can be determined by directly counting numbers of spermatozoa using a modification of the acridine orange direct count (AODC) technique for enumerating bacteria. A number of variables in the handling and processing of samples may bias estimates. Sample collection in glass and rapid fixation and filtration are necessary for reproducible estimates. Once filtered, samples are stable for many months, and counts on filters that were poorly stained …

Benthic algal blooms (e.g., Codium isthmocladum) have become increasingly common on reefs and hardgrounds of Southeast Florida. The contribution from possible responsible nutrient sources, including natural upwelling and local pollution, has not been quantified. In an attempt to differentiate each potential source, lattice-bound barium concentrations in the skeletons of two common Southeast Florida stony coral species (Montastraea faveolata and Solenastrea bournoni) were measured by isotope dilution inductively coupled mass spectrometry (ICP/MS). Specimens were collected offshore between 26˚01'-57'N at shallow (10m) and deep (20m) reefs. X-rays of skeletal slabs revealed annual density bands which guided annual and subannual …
