CBR spatial similarity analysis on mesoscale ocean eddies with remote sensing data

*Yunyan Du, Ce Li, Fenzhen Su, Tianyu Zhang & Xiaomei Yang


Ocean eddy Case-Based Reasoning (CBR) is developed and extended to the spatial-tempo domain in this paper to extract ocean eddy spatial similarity information in a quantificational manner, which can be very difficult to acquire using current routine eddy feature recognition and analysis algorithms. Present work includes three basic steps. First, information about the eddy’s spatial structure and attributes is obtained from the original remote sensing data. Then a library of historical eddy cases is built using the cases’ expression models. Finally, a Radius Vector Serial Analysis Model Based on Barycentre (RVSAMB) is provided to analyse the spatial similarity between the historical cases for further forecasting and dynamic analysis. In this study, a new quantitative method to analyse and extract ocean mesoscale eddy information using Case-based Reasoning is presented. Firstly, a historical ocean eddy case library was constructed based on the specific expression model. Then, the sketch of this method is discussed in detail, especially the similarity assessment method—“Radius Vector Serial Analysis Model Based on Barycentre”. Finally, a mesoscale warm eddy example in the Gulf Stream of the North Atlantic indicated that this is a feasible way to analyse ocean eddies.

Wave pressure reduction on vertical seawalls/caissons due to an offshore breakwater

M G Munireddy  and *S Neelamani


The technique to reduce the wave loads on seawalls/caissons is gaining momentum around the world. Placing an offshore structure in front of seawall/caisson is expected to reduce the loads on these structures. A series of physical model tests were carried out to examine the order of wave pressure reduction for different height of the breakwater related to the local water depth. One has to be careful, when the crest of the breakwater is immersed with about 17% of the water depth, during which, water jetting effect is found to increases the pressures. Modification factor in association with Goda`s formula is proposed to estimate the shoreward pressures on the seawall in the presence of the offshore breakwater. Statistical analysis is carried out on the measured pressure data and the wave pressures for 2% probability of exceedence for different breakwater heights w.r.t. the water depth are given in this paper.

Nitrogen and phosphorus in water and sediments at Ria Lagartos coastal lagoon, Yucatan, Gulf of Mexico

David S. Valdes* & Elizabeth Real


Ria Lagartos, a hypersaline coastal lagoon in the Gulf of Mexico on the Yucatan peninsula was sampled three times in a year at 30 locations, in order to quantify the nitrogen and phosphorus available in the water column and sediments. Undisturbed samples of sediment were analyzed and incubated in the laboratory to estimate ammonium and phosphate fluxes between water and sediment together with nitrification and denitrification rates. The results indicated higher ammonium liberation (250±149 mmol m-2 h-1) and nitrification (151±132 mmol m-2 h-1), than denitrification (47±33 mmol m-2 h-1). In contrast phosphate liberation from sediments was found to be low (0.67±1.31 mmol m-2 h-1). The high concentrations of organic matter (3.73±1.65 %), total nitrogen (99.14±62.73 mmol g-1), and phosphorus (4.42±1.82 mmol g-1) in the sediments of the lagoon, indicate that can be a sink for these elements.

Population dynamics of silver biddy Gerres setifer (Pisces: Perciformes) in the Parangipettai waters, southeast coast of India

*K Sivashanthini & S Ajmal Khan


Growth parameters of Gerres setifer (Hamilton, 1822) in the Parangipettai waters were estimated using ELEFAN I programme. The asymptotic length (L) and growth coefficient (K) were found to be respectively 174.05 mm and  1.19 year-1 respectively in male and 170.5 mm and 1.26 year-1 in female. The ‘t0’ estimated by substituting the Land K in Pauly’s equation was -0.0817 in males and -0.0775 in females. Instantaneous rates of mortality (Z), natural mortality (M) and fishing mortality (F) in male were 2.53, 1.26 and 1.26 while in females the above values were 2.80, 1.32 and 1.48. The results of the present study showed that exploitation of G. setifer in the Parangipettai waters is below the optimum level indicating scope for slight increase in catch efforts.

Growth inhibition of human pro-myelocytic leukemia (HL-60) cells by lipid extracts of marine alga Sargassum marginatum (Fucales, Phaeophyta) harvested off Goa (west coast of India)
with special reference to fatty acid composition

N Bhaskar,#* and M Hosakawa & K Miyashita


The present investigation deals with the fatty acid composition of total lipids and different lipid classes of brown seaweed Sargassum marginatum harvested off Goa. An effort was made to screen the growth inhibitiory/cytotoxic activity of lipid extracts on the human pro-melocytic leukemia (HL-60) cells. Phospholipids (PL) were found to be the most effective compared to the other lipid classes in terms of cytotoxic activity. PL exhibited cytotoxic activity at concentrations as low as 20 mg/ml. Phospholipids were found to be higher in poly unsaturated fatty acids (PUFA) among all the lipid classes analysed. This study indicates the possibility of seaweeds as potential sources of anticancer substances. Further works are needed to identify the active compound responsible for this anti-cancerous activity. The role of non-methylene interrupted (NMI) fatty acid specific to Sargassum spp, as anti-cancerous substance, also needs to be elucidated.

Immune enhancement assessment of dietry incorporated marine alga Sargassum wightii (Phaeophyceae/Punctariales) in tiger shrimp Penaeus monodon (Crustacia/Penaeidae) through prophenoloxidase (proPO) systems

S. Felix*, P. Herald Robins & A. Rajeev


An experiment of 30 days duration was conducted to test the efficacy of the seaweed Sargassum wightii, as immunostimulant in tiger shrimp Penaeus monodon. The shrimps were fed with the experimental diets coated with different concentrations of the brown algae S. wightii viz. 10, 20 and 30 g/kg. They were challenged with a marine pathogen Vibrio parahaemolyticus to assess the increase in survival rate if any due to immune enhancement. Another group of shrimp was used for drawing the haemolymph to estimate the increase in the level of prophenoloxidase activity. Samplings for the above said analysis were carried out at regular intervals of 3 days viz. 1st, 3rd, 6th, 9th and 12th days. The highest prophenoloxidase activity (0.62) and the highest survival rate (83%) were recorded on the 12th day with the experimental diet (10 g/kg) . Hence the 10 g/kg of S. wightii added to the diet could be an eco-friendly and economically viable immunostimulant for penaeid shrimps.

Abundance and distribution of cyanobacteria Synechococcus spp in the south-eastern Black Sea during 2001 summer

*A. Muzaffer Feyzioglu, Ilknur Kurt, Muhammet Boran, Nuket Sivri


Abundance and distribution of unicellular cyanobacteria Synechococcus spp were studied during July 2001. Samples were collected from four different depths covering above the thermocline. Nitrate concentrations ranged from 0,005 mg at-l-1 off Trabzon and Hopa to 1.284 mg at-l-1 off Giresun. The highest concentration of Synechococcus spp. was at off Giresun at 25 m (6000 cell ml-1) and off Rize (3700 cell ml-1) at suface. Cyanobacteria cell counts were low at 5 and 10 m depths. The picoplanktonic abundance varies with nutrients in the Black Sea and it is quite lower in July 2001 somewhat similar to those observed in the oligotrophic Atlantic waters.

Antibacterial activity of the winged oyster Pteria chinensis (Pterioida: pteridae)

C. Chellaram*, K. Mary Elizabeth Gnanambal & J.K. Patterson Edward


The whole body extracts of the winged oyster, Pteria chinensis obtained with different solvents were assayed for antibacterial activity using agar well diffusion technique against human and fish pathogens. The acetone and chloroform crude extracts exhibited broad antibacterial activity. Highest activity was exhibited against Klebsiella pneumoniae (5 mm) and Staphylococcus epidermidis (5 mm) by the crude extract of acetone and against Salmonella paratyphi B (5 mm) by the chloroform extract. Similarly, the crude extract of chloroform was found to inhibit 8 out of 10 fish pathogens tested. The column-purified acetone fractions showed higher activity against Klebsiella pneumoniae (5 mm), Sreptococcus pneumoniae (4 mm), Serratia marcescens (4 mm) and Proteus mirabilis (4 mm). The MIC of the 100% acetone fraction was found to be lower for the pathogens, S. marcescens (100 µg) and P. mirabilis (150 µg) and hence 100% acetonated fraction of the extract of P. chinensis can be considered as potent antimicrobial compound against these pathogens.
