0.139 ppb (n-pentane), 0.039 ppb (iso-pentane), 0.006 ppb (neo-pentane), and 0.179 ppb (acetylene). All showed a slight tendency to increase over the tropics. The sum of relative reactivities of these light hydrocarbons to methane was estimated to be about 26% of methane, which signifies that the effect of light hydrocarbons on atmospheric chemistry in the unpolluted troposphere can not be ignored.

Weather Forecasting, 7(2):273-279. At the Fleet Numerical Oceanography Center, two computer models, the Navy Operational Global Atmospheric Prediction System, NOGAPS, and the Navy Operational Regional Atmospheric Prediction System, NORAPS, generate a twice-daily suite of atmospheric analyses and forecasts . NOGAPS is the driving force behind many of the center's products and has become a complex, highly structured system designed to run automatically. The execution of NOGAPS and NORAPS within the operational schedule is described. The systems consist of automated data processing and quality control, a multivariate optimum interpolation analysis, initialization and forecast, and ou tput.

Weather Forecasting, 7(2):328-352.

The JTWC in Guam is the busiest tropical cyclone warning center in the world. Its areas of responsibility encompasses four broad oceanic areas of

tropical cyclone activity stretching from the international date line to the east coast of Africa, in both hemispheres. Our paper discusses the challenges imposed on the center as a result of its vast multi basin area of responsibility, the products the center produces, its warning philosophy, observational networks, analysis and forecast schemes, and the military aspects of the operation. The challenges of information and time management, an alysis and forecast improvement, expansion of meteorological understanding, and enhancement of the warning process are discussed. Current methods used to meet these challenges are presented. Naval Oceanogr.

The impact of SST anomalies on the dynamical long-range forecast of monthly mean fields in the early summer of 1983 is examined again. Shortcomings in the previous results (TYC 87) are eliminated by including SST anomalies over the Indian Ocean , using a modified Arakawa-Schubert cumulus parameterization and using the 15-layer model. In the tropics, anomaly correlation coefficients are high both in the first and the second month in the present study, while they are low in the second month in TYC 87. The model simulates the intraseasonal variation in the tropics. The forecast skill in midlatitudes for the second month is higher than that of TYC 87 both in the Northern and Southern hemispheres.

Global salinity patterns are examined using tbe 3.6 million measurements of MOODS. The major patterns found in this study confirm those established by earlier surveys. In some areas surface salinity shows annual variations dominated by river runoff or the Zehrung field (evaporation minus precipitation). In particular, salty water of the subtropical gyres extends down to 400 m in the North Atlantic. The Mediterranean is a significant source of salt to tbe Atlantic as deep as 3000 m, Below this, three water types are recognized by their salinity values. The greater overall salinity of the North Atlantic vs. the Pacific is attributed to greater poleward transport of surface waters in the Atlantic due to wind stress patterns. Salinity evidence for the 'global conveyor belt' of thermohaline circulation is also examined. Dept. of Earth, Atmos., and Planetary Sci ., 54-1824, MIT, Cambridge, MA 02139, USA. (rjw)

Benthic nitrogen cycling within sandy and silty substrates is examined at two stations in the southern North Sea. For both stations Oz consumption and ammonium release are highest during the summer months. Maximum denitrification occurs during spring with minimum rates in the fall. At both sites, >50% of the ammonium produced by benthic remineralization is regenerated to the water column. At the silty site, benthic nitrification supplies more than 85% of the nitrate needed for denitrification. The addition of detrital matter in mesocosms at both sites altered the nitrogen budget; system recovery occurred with in 2 months. Netherlands Inst. for Sea Res., P.O.

Transformation processes and advection have the potential to modify the transmission of surface signals to the deep sea. If these mechanisms overwhelm surface production signals , seasonal and annual variations in deep-sea geochemistry and biology would be controlled largely by lateral processes associated with ocean circulation rather than by surface processes. Here we report direct measurements of seasonal variations in upper-ocean primary production concurrent with particle fluxes

The productivity signal can be transferred rapidly to the deep sea by settling particles, yielding close temporal coupling between the surface and deep oceans. Ctr. for Mar. SeL, Univ. of So.

Deep-Sea Res; 39(6A):939-952.

Depth profiles of marine snow in the Panama Basin are obtained using a photographic technique. Results show that concentrations of aggregates are highest in surface waters and near the bottom. Mass fluxes based on aggregate abundances are several orders of magnitude larger than those measured by sediment traps and submersible pumps. These findings suggest that the observed aggregates are not responsible for particle fluxes in this area. A particle transport model is presented in which fast-sinking (relatively rare) aggregates are the chief mechanism of particle flux to the sea floor. Ctr. for Mar. SeL, Univ. of So.

This paper describes the development and testing of a linear density column that permits direct measurement of constituent matter density in particle aggregates in seawater. The density column is integrated into a system which also measures settling velocity and aggregate size and shape. Initial results include the first direct constituent density measurements of any type. Although settling velocity was not directly correlated with these measurements, as expected, they are considered valuable in constraining estimates of other physical properties of particle aggregates.

In samples from a water column profile taken in the North Pacific and the Bering Sea, two characteristic groups of proteins were identified from the vertical changes in their molecular distribution. The first, derived mainly from phytoplankton, was made up of a large number of proteins with widely ranging molecular weights. Concentrations of proteins in this group decreased rapidly with depth, indicating susceptibility to biological degradation. The second group included specific proteins distributed over a limited range of molecular weights. These were the most abundant protein constituents in particulate organic matter form the intermediate and deep waters, and may be resistant to biological attack, although the source and chemical nature of the specific proteins are not clear.

fractious in the north-central Pacific and Sargasso Sea. Nature, Lond.; 357(6380):667-670. We present a comparison of 6.14C (the deviation in ppt from the 14C activity of nineteenth-century wood) of the DOC measured by high-temperature catalytic combustion, DOC oxidizable by UV radiation, and humic substances in profiles from the oligotrophic north-central Pacific and Sargasso Sea. For each ocean, the AI4C values of all three fractions are remarkably similar, yielding no evidence for a component of DOC that is cycled through the system on timescales shorter than several thousands of years. We observe an age difference between the two oceans of -2000 yr for the deepest DOC, which can largely be accounted for by differences in the A14C of the DOC sources to the deep basins, and by the different deep-water circulation patterns and transit times in the two oceans.

The relationship between burrowing organisms and oxygenation of sediment is examined for two stations in the German Bight. Results show that oxygen transport through the burrow walls is linked to burrow structure and behavior of the burrowing organism. Oxygen concentration varies with the advective flow produced within the burrows during the 'irrigation phase' of organism activity. Irrigation intervals for one species were measured in pulses of 3 to 70 minutes. The total O2 flux budget for one site shows that approximately half of all oxygenation of sediments is through burrow walls.

'Seaweed farming' (macroalgal cultivation) as a means to enhance oceanic drawdown of atmospheric CO 2 is examined using a 3-D GCM. Results indicate that CO2 invasion from the atmosphere does not match carbon removal from the surface waters via sinking of fertilized organisms. In order to achieve the assumed enhanced growth of I Gt C yr l , a nutrient supply greater than the world's current fertilizer production would also be required. These findings suggest that seaweed farming is an inefficient scheme for sequestering anthropogenic CO2 , The suggested use of farmed macroalgae as an additional world fuel source would also result in a greater net transfer of CO 2 from the ocean to the atmosphere.

The molal concentrations of 34 elements in marine organisms were compared with the availability of these elements in their natural environment and some physico-chemical properties of the elements, viz. the charge /radius ratio or ionic potential and the 'noble gas deviation' or NOD-index, a value which expresses the deviation of the electron configuration of an element with that of the previous and subsequent noble gas configuration. The concentration factor (ratio of element concentration in biological material and in the environment) appears to be a periodic function of the element number, very similar to the NOD-index. The close fit between the concentration factor and the NGD·index offers, with some limitations, a possibility to assess the concentration factors of elements for which up till now no data have been available.

When it comes to the global carbon cycle, which at the moment can't even be balanced, carbon sources have been emphasized and carbon sinks ignored. This workshop sought to partially redress the balance by questioning the modellers' assumption of a steady state, identifying numerous potential carbon sinks not considered in the models, and by emphasizing that 'substantial potential exists for capturing and sequestering carbon in natural systems,' Separate sections are devoted to the (1) importance of carbon sinks, (2) effects of CO 2 on natural systems, (3) managing natural sinks, and (4) modelling carbon fluxes. Part 5 synthesizes the findings and makes recommendations for further work. (fcs)
