         2 . The system of  claim 1 , wherein the marine geophysical equipment comprises towed marine seismic streamers. 
     
     
         3 . The system of  claim 2 , wherein the marine geophysical equipment further comprises additional equipment attached to the marine seismic streamers. 
     
     
         4 . The system of  claim 1 , wherein the marine geophysical equipment comprises marine seismic sources. 
     
     
         5 . The system of  claim 1 , wherein the marine geophysical equipment comprises marine electromagnetic receivers. 
     
     
         6 . The system of  claim 1 , wherein the marine geophysical equipment comprises marine electromagnetic sources. 
     
     
         7 . The system of  claim 1 , wherein the surface covering comprises a modification of a surface of the towed geophysical equipment. 
     
     
         8 . The system of  claim 1 , wherein the surface covering comprises a coating applied to a surface of the towed geophysical equipment. 
     
     
         9 . The system of  claim 1 , wherein the surface covering protects the geophysical equipment from bio-foaling. 
     
     
         10 . The system of  claim 1 , wherein the surface covering reduces drag on the geophysical equipment. 
     
     
         11 . The system of  claim 1 , wherein the surface covering comprises surface elements in a pattern providing the textural attribute of an undulating surface texture similar to uneven texture of shark skin. 
     
     
         12 . The system of  claim 11 , wherein the pattern of surface elements replicates the dimensions of scales on shark skin. 
     
     
         13 . The system of  claim 11 , wherein the surface elements replicate the dimensions of scales on shark skin. 
     
     
         14 . The system of  claim 13 , wherein the surface elements further comprise parallel ridges and grooves. 
     
     
         15 . A system for gathering marine geophysical data, comprising:
 marine geophysical equipment, adapted for towing through a body of water; and   a surface covering, comprising a textural attribute that reduces bio-fouling, attached to the marine geophysical equipment.   
     
     
         16 . The system of  claim 15 , wherein the surface covering comprises surface elements in a pattern providing the textural attribute of an undulating surface texture. 
     
     
         17 . The system of  claim 16 , wherein the pattern of surface elements replicates the dimensions of scales on shark skin. 
     
     
         18 . The system of  claim 16 , wherein the surface elements replicate the dimensions of scales on shark skin. 
     
     
         19 . The system of  claim 18 , wherein the surface elements further comprise parallel ridges and grooves. 
     
     
         20 . A method for gathering marine geophysical data, comprising:
 towing marine geophysical equipment having a surface covering, comprising a textural attribute of shark skin, attached thereto.   
     
     
         21 . The method of  claim 20 , wherein the marine geophysical equipment comprises towed marine seismic streamers. 
     
     
         22 . The method of  claim 20 , wherein the marine geophysical equipment further comprises additional equipment attached to the marine seismic streamers. 
     
     
         23 . The method of  claim 20 , wherein the marine geophysical equipment comprises marine seismic sources. 
     
     
         24 . The method of  claim 20 , wherein the marine geophysical equipment comprises marine electromagnetic receivers. 
     
     
         25 . The method of  claim 15 , wherein the marine geophysical equipment comprises marine electromagnetic sources. 
     
     
         26 . The system of  claim 20 , wherein the surface covering comprises a modification of a surface of the towed geophysical equipment. 
     
     
         27 . The system of  claim 20 , wherein the surface covering comprises a coating applied to a surface of the towed geophysical equipment. 
     
     
         28 . The method of  claim 20 , wherein the surface covering protects the geophysical equipment from bio-foaling. 
     
     
         29 . The method of  claim 20 , wherein the surface covering reduces drag on the geophysical equipment. 
     
     
         30 . The method of  claim 20 , wherein the surface covering comprises surface elements in a pattern providing an undulating surface texture similar to uneven texture of shark skin.
