The existence of full-featured analysis tools, such as the Algorithm Development and Mining (ADaM) toolkit and online data repositories now provide easy access and analysis capabilities to large amounts of data. However, there are obstacles to getting the analysis tools and the data together in a workable environment. Does one bring the data to the tools or deploy the tools close to the data? The large size of many current Earth science datasets incurs significant overhead in network transfer for analysis workflows, even with the current advanced networking capabilities. We are developing two solutions for this problem that address different analysis scenarios. The first is a Data Center Deployment of the analysis services for large data selections, orchestrated by a remotely defined analysis workflow. The second is a Data Mining Center approach of providing a cohesive analysis solution for smaller subsets of data. The two approaches can be complementary and thus provide flexibility for researchers to exploit the best solution for their data requirements.

Geometric algorithms are designed for operations of type-2 fuzzy sets without using manner of upper or lower surfaces.

Polyunsaturated FA (PUFA) comprised 49–56% of the total FAs in algae from the Sea of Japan, while in algae from the South China Sea their share was 20% at most. The content of arachidonic acid (20:4n-6) in the total FAs of G. vermiculophylla was as high as 45.4%, while the level of 20:4n-6 in Gracilaria from coastal waters of Vietnam did not exceed 12.5%. G. austramaritima stood out for its high content of eicosapentaenoic acid 20:5n-3 (33.5%). The ratios of 20:4n-6/20:5n-3 in G. vermiculophylla, G. austramaritima, G. tenuistupitata, G. changii, and G. bailiniae were 10.6, 0.3, 3.9, 4.0, and 1.5, respectively. The content of PGE2 was the highest (286 μg/g dry weight) in G. vermiculophylla from the Sea of Japan and did not exceed 20 μg/g dry weights in other Gracilaria species. This study showed that it is possible to introduce G. vermiculophylla from the Sea of Japan into the mariculture of northern Vietnam. In the experiment, during 3 weeks of cultivation, the biomass of introduced Gracilaria increased 1.2–1.3 times in a sea lagoon in Vietnam and 1.5–2 times in an aquarium; the algal growth rates were 1.57 ± 0.21% per day. In cultivated Gracilaria, the level of 20:4n-6 decreased to 5.9% (20:4n-6/20:5n-3 = 2.3) and the level of PGE2 decreased to 12 μg/g in dry weight. The PUFA compositions of G. vermiculophylla from various natural populations differed insignificantly; however, the stress caused by introduction led to a sharp reduction in the content of 20:4n-6, which was probably connected with a decreased biosynthesis rate of PUFAs of the n-6 series. At the same time, approximately equal amounts of PGE2 methyl ester were extracted from natural and cultivated G. vermiculophylla after treatment by a method proposed for obtaining prostaglandins. Thus, the cultivation conditions evidently did not influence the prostaglandin biosynthesis enzyme complex in G. vermiculophylla; this species, when grown in mariculture, can be used as a source of prostaglandins.

The non-methylene-interrupted polyenoic fatty acids amounted to 12.0–26.4% of total acids. The distribution of triacylglycerols of the seeds according to their molecular weights was similar to that of common

Except for the Poritidae species, total lipids of the corals had the same set of FAs, about 50% of them being unsaturated acids. Some coral families had high levels of characteristic FAs: 20:3(n-6), 20:4(n-3), and 22:6(n-3) in Pocilloporidae; 18:1(n-9) and 22:6(n-3) in Poritidae; and 18:3(n-6) and 22:5(n-3) in Faviidae. For the first time in hexacorals, unsaturated C24 FAs (24:1(n-9), 24:2(n-6), 24:2(5,9), 24:3(5,9,17), and 24:4(n-3)) were discovered in the Poritidae species. The highest level of 18:1(n-7), odd-chain and branched FAs (7.5% in total) was detected in Sandalolitha robusta. The data obtained on the contents of ten principal C18–C22 polyunsaturated FAs (PUFAs) for the 16 specimens were combined with data on the 19 reef-building coral specimens investigated previously and subjected to multidimensional scale analysis (MSA). The representative coral families (Acroporidae, Pocilloporidae, Poritidae, Faviidae, Dendrophylliidae, and Milleporidae) were separated by MSA according to the composition of their principal PUFAs. Therefore, PUFAs may serve as chemotaxonomic markers for reef-building corals at the family level. Family-specific compositions of coral zooxanthellae characterized by different PUFA profiles, which affect the PUFA content of whole coral colonies, were supposed to be the probable cause of the discovered chemotaxonomic distinctions between reef-building corals.

The seed oil content varied between 0.2 g/100 g for Mangifera indica and 75.7 g/100 g for Calophyllum inophyllum, whereas only nine seeds contained more than 40% oil. The tocopherol content ranged from 26 (Sapindus mukorossi) to 9361 mg/kg (Litchi chinensis). In nine seed oils unusual FA such as conjugated, cyclopropenoic, or epoxy FA were found.

The contents of hydrocarbon, triacylglycerol, free fatty acid, sterol, di- and monoglycerol, and polar lipid fractions have been determined with a thin-layer chromatography (TLC)/flame-ionization detection analyzer. Molecular species of hydrogenated triacylglycerols and the fatty acid composition of total lipids also have been analyzed by capillary gas-liquid chromatography. The quantities of major phospholipid classes of four seed species(C. tora, I. aquatica, R. sativus, V. aurea) have been determined by two-dimensional TLC and the spectrophotometrical phosphorus analysis. The fatty acid compositions of nonpolar and polar lipid fractions of these four species also have been analyzed.
