Enes, From the looks of your code, you're creating "depth" as a double array (which mean 8 bytes for each value). With your dimensions (lat = 46391, lon=29912), that means the entire size of the array you're trying to allocate is: total = 46391 * 29912 * 8 = 11101180736 or 10.3 GB. You may be able to squeeze it in by using FLOAT instead of DOUBLE; that would cut your memory usage in half. I'm not sure if an approximately 5.1GB array would leave you enough room for other things to stay under the 6GB heap limit.
