SEAFLOOR DEPOSITS OF COBALT-RICH FERROMANGANESE CRUST WITHIN THE U.S. EXCLUSIVE ECONOMIC ZONE OFFER A POTENTIAL NEW MINERAL RESOURCE FOR STRATEGIC METALS. EVALUATION OF THESE DEPOSITS IS A PRIME OBJECTIVE OF CURRENT AND PLANNED DEPARTMENT OF INTERIOR RESEARCH EFFORTS. PRESENT CRUST SAMPLING DEVICES ARE INADEQUATE FOR EFFICIENT RESOURCE ASSESSMENT. THE DEVELOPMENT OF A TETHERED, MULTI-SAMPLE CORING ...

THIS PROJECT WILL EXAMINE THE PROCESS OF WAVE EROSION OF FROZEN OR PARTIALLY FROZEN SLOPES. THE SPECIFIC APPLICATION IS THE EROSION OF UNPROTECTED CAUSEWAY BERMS BEING CONSTRUCTED IN THE ARCTIC. THE RATE EROSION, THE NEED FOR SLOPE PROTECTION (OR NON-NEED), AND THE TYPE OF SLOPE PROTECTION REQUIRED WILL BE IDENTIFIED. THE TEST WILL BE CONDUCTED AT PROTOTYPE SCALE TO CORRECTLY MODEL THE THERMAL ERO ...

SUBSEA OIL AND GAS PRODUCTION SYSTEMS ARE FINDING INCREASING APPLICATION AS THE DEPTHS AND ENVIRONMENTS FROM WHICH PRODUCTION WILL TAKE PLACE BECOME MORE DEMANDING. SOME OF THESE ENVIRONMENTS, SPECIFICALLY THE ARCTIC, WILL NOT PERMIT UTILIZATION OF CONVENTIONAL UNDERWATER INTERVENTION TECHNIQUES OWING TO THE ICE COVER. TO ASSURE SAFE AND POLLUTION-FREE OPERATION OF THESE STRUCTURES WILL REQUIRE DE ...

INTEREST HAS DEVELOPED IN THE REDUCTION OF MINERALS BY A 150KW LABORATORY MODEL OF THE ROTARY PLASMA ARC FURNACE (RPAF) PARTICULARLY FOR CONTINUOUS PREPARATION OF FERROCHROMIUM FROM DOMESTIC CHROMITE FINES. ALL SUPPORT, TO DATE IS IN PROCESS DEVELOPMENT BUT A LARGER IMPROVED PROTOTYPE IS NEEDED FOR IMPROVED FURNACE COMPARISON DATA. THIS IS A DIFFICULT DESIGN PROBLEM BECAUSE OF THE HIGH SENSITIVITY ...

SURFACE DEVELOPMENT HAS LED, IN SOME CASES, TO REDUCING THE QUALITY OF GROUND-WATER. IN AN EFFORT TO MORE FULLY UNDERSTAND THE INTERACTIONS INVOLVED AND TO BETTER PREDICT HARMFUL SURFACE DEVELOPMENT RESULTS, C.A.D.D. CORP. PLANS TO ACCUMULATE AND VERIFY INFORMATION CONCERNING TYPES OF LAND USE, POPULATION, DISTRIBUTION, WASTE DISPOSAL AND RELATED INFORMATION FOR THE AREA. INFORMATION WILL BE OBTAI ...

THERE IS A NEED FOR DEVELOPMENT OF A COMMERCIALLY AVAILABLE ECONOMICAL ACOUSTIC DOPPLER BACKSCATTER INSTRUMENT WHICH CANBE EASILY DEPLOYED AND USED TO SIMULTANEOUSLY ACQUIRE CURRENT PROFILE DATA AND BACKSCATTER AMPLITUDE INFORMATION RELATING TO PARTICLE CONCENTRATIONS IN THE WATER COLUMN. THE RESEARCH PROPOSED IN PHASE I IS DIRECTED AT TWO AREAS OFDOPPLER BACKSCATTER MEASUREMENT WHERE ADVANCES IN ...

THE COMBINATION OF VECTOR (OR LINE-ORIENTED) AND RASTER (IMAGE-ORIENTED) COMPUTER GRAPHICS HARDWARE AND SOFTWARE TECHNIQUES WOULD GREATLY IMPROVE THE PRODUCTIVITY AND USEFULNESS OF GEOGRAPHIC INFORMATION SYSTEMS. WHILE EXPLORATORY WORK IN THIS AREA HAS BEEN DONE SINCE ABOUT 1975, IT HAS BEEN COMPROMISED BY LIMITATIONS OF BOTH DISPLAY EQUIPMENT AND SOFTWARE DEVELOPMENT TOOLS. THE INTENT OF THIS PRO ...

GENAVE SHALL INVESTIGATE A RADIO TRACKING SYSTEM WHICH MO MONITORS WILDLIFE. THE EFFORT WILL BE DIRECTED TOWARD DEVELOPING A SYSTEM WHICH WILL WORK WITH EXISTING TRANSMI TRANSMITTERS AS WELL AS WITH A UNIQUE PHASING TECHNIQUE WHICH IS AUTOMATICALLY GENERATED BY THE TRACKING ANTENNA AND WILL GIVE RANGE DATA FROM A SINGLE ANTENNA.

THIS PROPOSAL IS TO MODEL THE TRANSPORT OF POLLUTANTS IN UNSATURATED POROUS MEDIA FLOW. THE MODEL TO BE USED WILL BE A THREE-DIMENSIONAL UNSATURATED-SATURATED FLOW MODEL COUPLED WITH A THREE-DIMENSIONAL CONVECTION-DISPERSION EQUATION. THE MODEL WILL BE IMPLEMENTED ON A CDC CYBER 205 SUPERCOMPUTER WHICH HAS THE SIZE AND SPEED NECESSARY TO MAKETHIS APPROACH A REALITY. PHASE I OF THE PROJECT WILL BE ...

WHEN IT IS NECESSARY TO RAISE A MARINE PIPELINE FOR REPAIR DUE TO TRAWLER SNAG, ETC., THE PIPELINE WILL BUCKLE, AND THEN THE BUCKLE WILL PROPAGATE IF ALL CONDITIONS ARE NOT PROPER. WITH SEVERE BUCKLES, THE PIPE WILL BREAK OPEN ALLOWING THE OIL TO SPILL. THIS CAN BE MINIMIZED BY PERIODICALLY PLACING REMOTELY OPERABLE VALVES IN THE LINE FOR CUTOFF. BUT SOMETIMES THE PIPELINE ROTATES AS IT IS BEING L ...
