Laboratory Setup https://www.gulfbenthos.org/apps/photos/ Laboratory Setup Laboratory set up for sorting A stereoscopic dissecting microscope with 120x magnification is used (10x eyepieces and 12 x objective). https://www.gulfbenthos.org/apps/photos/photo?photoID=176316014 176316014 Light component A gridded plastic dish is used for sorting the sample. https://www.gulfbenthos.org/apps/photos/photo?photoID=176316010 176316010 Light component ready for sorting A small portion at a time is spread evenly across the gridded dish. https://www.gulfbenthos.org/apps/photos/photo?photoID=176316013 176316013 Light component under the scope. The sample is systematically examined and animals are removed to a labeled bottle of 70% ethanol for later taxonomic identification. https://www.gulfbenthos.org/apps/photos/photo?photoID=176316015 176316015 Coarse component These large detritus fragments from the coarse component of the sample will be examined for encrusting organisms such as barnacles or tunicates. https://www.gulfbenthos.org/apps/photos/photo?photoID=176316011 176316011 Coarse material set up for examination Sand and shell hash is examined under low magnification for heavier-bodied organisms such as tubiculous polychaetes and mollusks, while dragging material from one end of the dish to the other through a small film of water. https://www.gulfbenthos.org/apps/photos/photo?photoID=176316012 176316012
