I have only eastward sea water velocity and northward sea water velocity.
With this two data, how can I calculate ocean current speed?
the data is from https://resources.marine.copernicus.eu/product-detail/SEALEVEL_GLO_PHY_L4_NRT_OBSERVATIONS_008_046/INFORMATION

Let u and v be the components.
s = sqrt(u.^2+v.^2)

@민준 배, since you are asking for velocity and not speed and have orthogonal velocities that I assume match your frame of reference you already have the answer. If you want direction and speed, @KSSV has provide the speed calculation above, and if the direction is to be in local compass where N=0, E=90 etc:
velN = -30;
velE = +20;
speed = norm([velE velN])
direction = atan2d(velE,velN)
