  We present results from optical narrow-band lambda_c = 8150A ~ and Delta
lambda = 120A) observations of the Great Observatories Origins Deep Survey
(GOODS) fields, using Suprime-Cam on the Subaru Telescope. Using these
narrow-band data, we then perform a survey of Lyman alpha Emitters (LAEs) at
z~5.7. The LAE survey covers an area of approx 320 arcmin^2 and a co-moving
volume of ~8.0 x 10^4 Mpc^3. We found a total of 10 (GOODS-N) and 4 (GOODS-S)
LAE candidates at z~5.7. We perform a study of the spatial distribution, space
density, and star formation properties of the LAEs at z~5.7.
