AbstractSurface temperature is one of the first ocean variables investigated. Ocean temperature is a key indicator of global climate change. The anomalies in ocean temperature have caused significant deterioration of marine systems. Existing works on surface temperature anomaly considered a suite of other remote sensing measurements such as wave height, salinity and models such as support vector machine, self-organizing maps and convolutional neural networks. Neural networks are used for predicting the surface temperature. This paper proposes use of long short-term memory, a recurrent neural network method to the estimate sea surface temperature anomalies based on previous year?s sea surface temperature anomalies. NOAA OI SST V2 dataset with 40 years of data is used in the experimentation. Auto-regression is used during data preprocessing. The basic LSTM method with 3 blocks of size 2 is enhanced to 50 neurons. This proposed LSTM model has been assessed for performance on time series data, yearly wise and for the entire dataset and found that the model has been able to predict the anomalies with a reasonably good precision. The model produced error of 0.036 indicating that the model is feasible for predicting the temperature anomaly and mean absolute error of 0.14 on the testing data.

TitlePSNM: An Algorithm for Detecting Duplicates in Oceanographic Data
Authors L. Srinivasa Reddy, S. P. Vighneshwar, B. Ravikiran

AbstractThis work discusses a new method of identifying duplicates in surface meteorology data using PSNM (Progressive Sorted Neighborhood Method) Algorithm. Duplicate detection is the process of identifying the same representations of the real world entities in the data. This method needs to process a large amount of ocean data sets in shorter time. PSNM algorithm increases the efficiency of finding duplicates with lesser execution time and get the efficient results much earlier than traditional approaches. It is observed that all possible duplicates associated with the data can be identified using this method, and also this work proposes a new way to access the resulted (Duplicate eliminated) data using authorization restrictions based on the type of user and their need with different file conversion formats.

TitleTime Series Analysis of Oceanographic Data Using Clustering Algorithms
Authors D. J. Santosh Kumar, S. P. Vighneshwar, Tusar Kanti Mishra, Satya V. Jampana

AbstractWith the availability of huge data sets in device fields like finances to weather, it becomes very important to quality analysis and interprets the results. In such scenario K-Means and DBSCAN clustering algorithms are used for effective data grouping to get insight into the hidden structure in the data. In this paper focus on the application of clustering to ocean data observations. An attempt is made to correlate the resulting clusters to the variability focused during cyclones.

AbstractIn this paper, we focus on implementation of research, and the efficient management of resulting Indian ocean data. Data management and integration consider the careful collection, management and dissemination of research data is taken to provide vast ocean information integration. In order to develop robust ocean information system, the data from in-situ ocean observing systems such as Argo floats, drifting buoys, moored buoys, XBT surveys, tide gauges, coastal radars, current meter mooring array, bottom pressure recorders has been considered to design by implementing data acquisition, processing, quality control, and database generation. The diverse data sets has been acquired from in-situ platforms needs to be quality controlled, organized and disseminated in real time to data users. This paper on ODIS provides ocean data management and web-based ocean information system and its visualization functions for oceanographic data. An integrated observing system will also require improved combination of data from in-situ platforms which observations depends on their parameters and data types.
