The Gulf Stream by the Coast Survey. Based on a series of studies beginning in 1845. The Coast Survey established a number of sections for repeated observations. The first systematic oceanographic studies of the Gulf Stream. Integrated oceanography, marine geology, and meteorology into these cruises |

Steam winch with steel wire. Steel wire for deepsea dredging was first used on the BLAKE. This innovation was the result of collaboration between Charles D. Sigsbee and Alexander Agassiz. It was Agassiz's idea to replace hemp rope with steel cable mining technology. In: "Deep-Sea Sounding and Dredging", by Charles D. Sigsbee. 1880. Plate 30, p. 152. Call Number GC75 .S53. |

Diagram of possible sound wave paths in water. Wave-path O-C-E came close to describing refractive path of sound in SOFAR layer . Sound path model developed in 1930's for radio acoustic ranging work. Didn't yet understand the channeling effect of the velocity minimum. Furthest RAR use was out to 206 miles offshore in 1925 |

C&GS Ship PIONEER under Golden Gate Bridge. Magnetometer invented at Scripps deployed on this ship in late 1950's. Surveys from Pt. Conception to Cape Flattery discovered magnetic striping. Magnetic striping led to Theory of Seafloor Spreading. H. W. Menard called "among most significant geophysical surveys ever made" |
