Seawater may be considered a heterogeneous mixture because contain many insoluble materials.
Seawater is water (H2O which is a compound) containing soluble compounds but also insoluble materials. We can consider, with approximation, that the seawater is a homogeneous solution.
Yes, seawater is a solution made up of several elements and compounds dissolved in water, such as salt (sodium chloride), magnesium, and calcium. It is considered a homogeneous mixture.
