POPLAR was Project 3.7. Scaevola SCAEVOLA predicted fallout, surface radiological exclusion (radex) area, ship positions, and aircraft participation. Scaevola was detonated on July 14, 1958, at 1600. Scaevola was detonated on a barge west of Runit Island at Enewetak. Its yield was low and the explosion did not destroy the shot barge but only damaged it, producing a yield range. No DOD-sponsored experiments were scheduled for Scaevola. Pisonia PISONIA predicted fallout, surface radiological exclusion (radex) area, ship positions, and aircraft participation. PISONIA was detonated on July 18, 1958, at 1100. PISONIA was detonated on a barge west of Runit Island at Enewetak. The cloud rose immediately to , and produced a yield range. No DOD-sponsored experiments were scheduled for PISONIA. Juniper JUNIPER predicted fallout, surface radiological exclusion (radex) area, ship positions, and aircraft participation. JUNIPER, the last nuclear detonation to occur at Bikini, was detonated on July 22, 1958, at 1620. JUNIPER was detonated on a barge from the west end of Eneman in the ZUINI crater at Bikini . The detonation cloud rose to with an estimated base, and produced a yield range. No DOD-sponsored experiments were scheduled for JUNIPER. Olive OLIVE predicted fallout, surface radiological exclusion (radex) area, ship positions, and aircraft participation. OLIVE was detonated on July 23, 1958, at 0830. OLIVE was detonated on a barge southwest of Enjebi Island, at Enewetak Atoll. from the nearest land at Enewetak. The cloud rose to with an estimated base, and produced a yield range. No DOD-sponsored experiments were scheduled for OLIVE. Pine PINE predicted fallout, surface radiological exclusion (radex) area, ship positions, and aircraft participation. PINE was detonated on July 27, 1958, at 0830. PINE was detonated on a barge southwest of Enjebi Island, from the nearest land, at Enewetak. The cloud rose quickly to with an estimated base as measured by radar, and produced a yield range. No DOD-sponsored experiments were scheduled for PINE. Underwater tests Underwater tests were conducted to assess the damages to Navy boats and materials. The location for these tests was Enewetak due to the uniformity of the sea bottom in the area. This is critical for the tests so that proper moorings of the target ships can be secured on the sea floor. The underwater explosions create a bubble from the expended energy of the blast. This bubble is due to the vaporization of water that directly absorbs the heat of the
