Timeline of United States discoveries 4–6, 1942 and the decisive turning point of the Pacific War when the United States Navy defeated an attack by the Empire of Japan. First known as "Middlebrooks Islands", Midway Atoll was discovered by U.S. Captain N.C. Brooks aboard his ship, "Gambia", on July 8, 1859. 1859 Petroleum jelly Petroleum jelly, petrolatum or soft paraffin is a semi-solid mixture of hydrocarbons originally promoted as a topical ointment for its healing properties. The raw material for petroleum jelly was discovered in 1859 by Robert Chesebrough, a chemist from New York. In 1870, this product was branded as Vaseline Petroleum Jelly. 1873
Jelly-falls of Norway on natural jelly-falls also revealed caridean shrimp feeding on jelly carcasses. Finally, decomposition is aided by the microbial community. In a case study on the Black Sea, the number of bacteria increased in the presence of jelly-falls, and the bacteria were shown to preferentially use nitrogen released from decaying jelly carcasses while mostly leaving carbon. In addition, with the exclusion of scavengers, jelly-falls develop a white layer of bacteria over the decaying carcasses and emit a black residue over the surrounding area, which is from sulfide. This high level of microbial activity requires a lot of oxygen, which
