We explore the known connection of Kloosterman sums
on fields of characteristic 2 and 3 with the number of points
on certain elliptic curves over these fields.
We use this connection to prove results on the divisibility
of Kloosterman sums, and to compute numerical examples
of zeros of Kloosterman sums on binary and ternary fields of large orders.
We also show that this connection easily yields some formulas due to Carlitz
that were recently used to prove certain non-existence results
on Kloosterman zeros in subfields.
