Yes definitely. the geographical ranges of many species of seaweed and animal is moving. there are southern species such as Phorcus lineatus whose range is extending approximately 10 miles per year further north as the waters warm.
most species have a thermal limit that they can tolerate before it is either to warm or to cold for them to survive and produce offspring. having a warmer sea means that we are seeing animals respond to this change by moving increasing their range north (if they like warm waters) or their range is shrinking (if they like cold waters.) the full effects of this are still very badly understood however.
