This may seem like a very simple request, but does anyone have or know where I can get a shapefile of the ocean around the US? The only thing I can find within my ArcGIS BA is the ocean background, which doesn't do me much good when I'm trying to cover up heat map data.
If this is not possible can someone tell me how to convert a raster (heat map) to a shapefile?

Both land and ocean shapefiles can be found at Natural Earth: http://www.naturalearthdata.com/downloads/110m-physical-vectors/
