1897-1900 Student at Cambridge University (gained Masters degree in 1902)
1900-Mar 1902 Assistant to Sir Charles Eliot (British Consul-General at Zanzibar, Commissioner for East African Protectorate, and specialist in nudibranches, collecting and studying marine fauna in Zanzibar

1905-1922 Director of the Sudan Pearl Fishery
1923 Scientific research in England
1924-1926 Joined the St George expedition to the South Pacific in 1924, visiting the Panama region, Galapogas and Marquesas, before leaving the expedition at Tahiti, where he continued to study marine ecology and coral
1927 Scientific research in England

1930-38 Established and directed a marine biological station at Ghardaqa on the Red Sea Coast, at the request of the Egyptian Government. During this time, he also participated in an oceanographical expedition to the North West Indian Ocean, in the Egyptian Steamer 'Mabahiss'
1938-1943 Moved to Denmark with his wife and son, continuing scientific work at the University of Copenhagen's Zoological Museum until his death
Crossland discovered over one hundred new species; two genera and around twenty-five species are named after him. Including small notes, he published about fifty titles, thirty of which are purely scientific in nature.
Crossland's interest in protozoa, begun during his years as assistant to MacIntosh, continued throughout his career. He published seven papers on protozoa, all concerning species from the Red Sea, East Africa, Zanzibar the Maldives and the Cape Verdi Islands. However, Crossland is best known for his influential work on corals and coral reefs, including his important paper 'On Forskals's Collection of Corals in the Zoological Museum of Copenhagen', and his ecological studies of Zanzibar, Tahiti and the Red Sea. Few scientific papers result from his stay on the Sudan Coast; his large manuscript on the biology and cultivation of the pearl oyster never found publication.
