The gut contents of Undinulu vulgaris (a Calanoid copepod) collected from Eniwetok lagoon consisted of about 95% detritus with only 2% of the gut material fluorescing as chlorophyll.That of Oikopleum Zongicauduta (a larvaccan) consisted of about 89% detritus with only 6% fluorescing as chlorophyll.

The history surrounding the identity of Cletocamptus albuquerquensis (Herrick, 1894) and C. dominicanus Kiefer, 1934 is very complex. This complexity has been exacerbated by incomplete, and in some cases erroneous, original descriptions of these two species. Also, new records from other locations did not describe the significant characters needed to clearly delineate them. This led several authors to consider C. dominicanus as a synonym of C. albuquerquensis, among other taxonomical considerations regarding, for example, the status of Marshia brevicaudata Herrick, 1894. Inspection of biological material from Saskatchewan (southern Canada), Wyoming (central US), Trinidad and Tobago, and the British Virgin Islands, identified by other researchers as C. albuquerquensis, as well as of newly collected material from Great Salt Lake (Utah, central US), Puerto Rico, Culebra Island, Vieques Island, St. John Island (US Virgin Islands), San Salvador (Bahamas), and Santa Marta (Colombia), revealed that C. albuquerquensis and C. dominicanus are distinct and identifiable species, distributed in a more restricted area than previously thought. Additionally, we describe a new species, C. tainoi sp. nov., from St. John Island (US Virgin Islands), and we propose another new species, C. chappuisi sp. nov., for two males from Bonaire previously identified as C. albuquerquensis. Finally, we give some observations on tube-pore-like structures, previously overlooked, on the endopod of the male leg three.

The fate and effects of two nearshore discharges of Murban crude oil at Long Cove, Searsport, Maine in August 1981 were studied following a one-year, pre-spill baseline study of the test areas. An upper and a lower intertidal sampling area within a 60 × 100 meter test plot were exposed to dispersed oil in water resulting from the discharge of 250 gallons of oil pre-mixed with 25 gallons of Corexit 9527 dispersant. Release of treated oil was around high-water slack tide on the surface of the water, with added mixing energy provided by mixing gates deployed by small boats. The maximum water depth over the test areas was 3.5 meters. Untreated crude oil (250 gallons) was released on an ebbing tide within a separate, boomed-off 60 × 100 meter test plot. A third test plot served as an oil-free reference plot. Water samples taken near the surface and near the bottom during and after discharge showed that chemically dispersed oil loses lower boiling hydrocarbons in both the aliphatic and aromatic fractions below n-C17as the droplets diffuse downward. Data are given for sediment samples taken from the test plots 11 months pre-spill and 10 months post-spill. Hydrocarbon analyses of the sediment samples show little incorporation of dispersed oil into the sediments of the treated oil plot relative to the sediments exposed to undispersed oil.
