Many thanks, Ethan (and Jon Blower). However, although I no longer get an error when using EPSG:3857, I now get a blank map. Here is an example that works in EPSG:4326 (gives a green map of SST) but gives a blank map in EPSG:3857. - http://oos.soest.hawaii.edu/thredds/wms/hioos/roms_forec/hiig/HI-ROMS_Forecast_Model_Run_Collection_best.ncd?SERVICE=WMS&REQUEST=GetMap&VERSION=1.3.0&LAYERS=temp&STYLES=boxfill/rainbow&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=true&BBOX=-160.3125,16.63619187839765,-157.5,19.31114335506464&WIDTH=256&HEIGHT=256&CRS=EPSG:4326&ELEVATION=-0.016666666666666666&TIME=2011-04-05T00:00:00Z&NUMCOLORBANDS=256&COLORSCALERANGE=23.0,27.0 - http://oos.soest.hawaii.edu/thredds/wms/hioos/roms_forec/hiig/HI-ROMS_Forecast_Model_Run_Collection_best.ncd?SERVICE=WMS&REQUEST=GetMap&VERSION=1.3.0&LAYERS=temp&STYLES=boxfill/rainbow&FORMAT=image/png&BGCOLOR=0xFFFFFF&TRANSPARENT=true&BBOX=-160.3125,16.63619187839765,-157.5,19.31114335506464&WIDTH=256&HEIGHT=256&CRS=EPSG:3857&ELEVATION=-0.016666666666666666&TIME=2011-04-05T00:00:00Z&NUMCOLORBANDS=256&COLORSCALERANGE=23.0,27.0 In addition, here are two GetMetadata examples.
