The U. S. Marine Corps leased the old Curtiss Flying Field from Glenn Curtiss for $1 a year for use in training Marine aviators how to fly. The Marine Flying Field was in operation from March 1918 until September 25, 1919.

Some research notes- from:
http://www.history.navy.mil/content/dam/nhhc/research/publications/1910/2%20Chapter2.pdf
"10 FEBRUARY 1918• The Marine Aeronautic Detachment, Capt. Roy S. Geiger, USMC, commanding, transferred to operate water-based aircraft from Marine Barracks, Philadelphia Navy Yard, Pa., to NAS Miami, Fla. The detachment consequently moved to nearby Marine Flying Field, Miami."
My comment: something doesn't in the above document doesn't jive because the photo shows land-based aircraft and the official Navy history documents says "water-based aircraft." Hmmmm
Then I discovered this:
"31 MARCH 1918 • The First Aviation Squadron transferred from Gerstner Field at Lake Charles, La., to Marine Flying Field, Miami, Fla." I presume these are the land-based aircraft in the photo.
And then I discovered this:
"15 APRIL 1918 • The First Marine Aviation Force, Capt. Alfred A. Cunningham, USMC, commanding, was formed with men of the First Aviation Squadron and the Aeronautic Detachment, USMC, at Marine Flying Field, Miami, Fla. The latter two commands had disbanded the day before. A headquarters company and four squadrons, designated A, B, C, and D, were organized within this force on 16 June. These squadrons later deployed to France and operated as the Day Wing of the Northern Bombing Group, where they subsequently received the designations of 7 through 10. These squadrons normally comprised an authorized strength of 18 planes each."
And more regarding NAS Miami:
"18 MAY 1918 • The Chief of Naval Operations set training goals to provide pilots for foreign service and directed that eight elementary training squadrons be operated—two at Bay Shore, N.Y., two at Key West, Fla., and four at Miami, Fla. He also directed that elementary training at Pensacola, Fla., be discontinued as soon as the students on board had graduated, and that six advanced training squadrons be organized there to begin training patrol plane and night bomber pilots as soon as practicable."
And then the Marines in Europe returned to Marine Flying Field Miami:
"24 JANUARY 1919 • The Marines at Ponta Delgada, Azores, received orders to abandon their station and return to the United States. On 17 March 1919 the men arrived at Marine Flying Field, Miami, Fla."
