A marine information collection system comprises: an anchor (1) which is positioned on the ocean floor; an intermediate buoy (2) which is connected to the anchor (1) and floats in the water; a mooring cable (3) which is connected at one end to the intermediate buoy (2); and an observation buoy (4) which is connected to the other end of the mooring cable (3). The observation buoy (4) further comprises: a main body part (41), the longitudinal direction thereof being positioned in the direction of the progression of the ocean current; a specific gravity adjustment part (42) which is positioned in the main body part (41) and is provided with an inflatable float bladder (42a); an antenna (43) which is positioned in the main body part (41) and carries out a data transfer; and an observation part (44) which is positioned in the main body part (41) and acquires prescribed marine information. The observation buoy (4) is made to rise by inflating the float bladder (42a) of the specific gravity adjustment part (42), and made to descend by deflating the float bladder (42a) of the specific gravity adjustment part (42), thus being made to remain in place in the water. It is possible to easily make the buoy rise and sink, as well as to remain in place in the water.
