A list of all known polychaete species reported in the primary literature is presented for the Caribbean Sea. The most spe-cies-rich polychaete faunas are those of Cuba in the North Caribbean ecoregion and Trinidad-Tobago and Colombia in theSouth Caribbean ecoregion while the ecoregion with the greatest number of species is the Greater Antilles. While part ofthe explanation for these higher diversity areas may be due to collection effort, these areas may also be higher in speciesnumber as a result of being ecotones between the Gulf of Mexico in the north and the northern South American region tothe south. The most species-rich families are the Syllidae, Eunicidae, Nereididae, Polynoidae, Sabellidae, Serpulidae, Ter-ebellidae, and Spionidae. A brief discussion of the history of polychaete research identified many of the more importantworkers in the characterization of the polychaete fauna of the region. An analysis of the species-record accumulation curvefor polychaetes indicated that this fauna has not yet been fully characterized. One portion of the polychaete fauna identified as being especially poorly known is that from the deep-water areas of the Caribbean.

Industrial microwave heating technology has emerged as a new ceramic processing technique. The unique advantages of fast sintering, high density, and improved materials properties makes it superior in certain respects to other processing methods. This work presents the structure characterization of a microwave sintered ceramic matrix composite.Commercial α-alumina powder A-16 (Alcoa) is chosen as the matrix material, β-silicon carbide whiskers (Third Millennium Technologies, Inc.) are used as the reinforcing element. The green samples consisted of 90 vol% Al2O3 powder and 10 vol% ultrasonically-dispersed SiC whiskers. The powder mixture is blended together, and then uniaxially pressed into a cylindrical pellet under a pressure of 230 MPa, which yields a 52% green density. The sintering experiments are carried out using an industry microwave system (Gober, Model S6F) which generates microwave radiation at 2.45 GHz with a maximum output power of 6 kW. The composites are sintered at two different temperatures (1550°C and 1650°C) with various isothermal processing time intervals ranging from 10 to 20 min.
