We present the discovery of three new Scattered Kuiper Belt Objects ( SKBOs ) from a wide-field survey of the ecliptic .
This continuing survey has to date covered 20.2 square degrees to a limiting red magnitude of 23.6 .
We combine the data from this new survey with an existing survey conducted at the University of Hawaii 2.2m telescope to constrain the number and mass of the SKBOs .
The SKBOs are characterized by large eccentricities , perihelia near 35 AU , and semi-major axes > 50 AU .
Using a maximum-likelihood model , we estimate the total number of SKBOs larger than 100 km in diameter to be N = ( 3.1 ^ { +1.9 } _ { -1.3 } ) \times 10 ^ { 4 } ( 1 \sigma ) and the total mass of SKBOs to be M \sim 0.05 M _ { \oplus } , demonstrating that the SKBOs are similar in number and mass to the Kuiper Belt inside 50 AU .
