 reurely moderate on the control panels eind trom traces to moderate on 

 the test peinels. 



2. Algae . Algae, ranging from a trace to a light growth, occurred 

 on 2 of the test panels at the Naval Station. 



5. Invertehrate animal phyla . 



a. Coelenterata (hydroid s ) . Hydroids occurred vith great 

 frequency at hoth locations. At the Fuel Facility, they vere on 27 of 

 the 50 control panels and on all 30 of the test panels. At the Naval 

 Station, they appeared on 19 of the 58 control panels and on 50 of the 

 k^ test panels. They ranged from traces to light growths on the panels 

 of "both series. Tuhularia occurred with great frequency and was the 

 only form identified. 



Tj. Bryozoa (encrusting and filamentous) . Encrusting Bryozoa 

 occurred more or less abundantly at "both locations hut with greater 

 frequency at the Fuel Facility. At this location, they occurred on I6 

 of the 50 control panels euad on 25 of the 50 test 'panels; ■vdiile at the 

 Naval Station, they occurred on only 2 of the 58 control panels and on 

 Ik of the ^5 test panels. At the Fuel Facility, one of the control 

 panels, which inadvertently was left submerged for 5 months, was 90^ 

 covered , and 5 of the ttest panels were from 50^ to 90^ covered after 

 2 to 9 months' submergence. One test panel was 80^ covered in 2 months, 

 and 2 were 90'?^ covered in 5 months. Cryptosula pallasiana , Electra sp., 

 Holoporella "brunnea , LichenoT>ora sp . , Rhynchozoon tumulosum, Schizoporella 

 unicornis , Schizoporella sp., and Tegella sp. were identified. Filamentous 

 Bryozoa also occurred more or less alDundantly at "both locations "but with 

 greater frequency at the Fuel Facility. At this location, they occurred 

 on 16 of the 50 control panels emd on 25 of the 50 test panels; while at 

 the NavaJL Station, they occurred only on 11 of the U5 test panels. Bugula 

 flabellata and Bugula sp. were the only ones identified. 



c. Annelida (annelid worms) . Serpulid ( Serpula) worms occurred 

 with great frequency at both locations, At the Fuel Facility, they were 

 on 16 of the 50 control panels and on 2k of the 50 test panels; \*ile at 

 the Naval Station, they appeared on ik of the 58 control pa,nels and on 29 

 of the k^ test panels. At the Fuel Annex, 7 of the control panels were 

 from 50^ %o 100^ covered and k of the test panels were from 50^ to 100^ 

 covered.- At the Nayal Station, k of the control panels were from 10^ to 

 100^ covered and 19 of the test panels were from 10^ to 90^^ covered. 

 Maximum lengths of 5^5 mm were recorded on a control panel and 60 mm on a teel 

 panel after 5 months* submergence. Balanus (barnacles) occurred with 

 great frequency at both locations. At the Fuel Facility, they were on ik
