Most of the ocean floor is still not mapped to modern high-resolution standards, and even less has been visually explored in detail.

Why it matters

The idea in context

Sonar lets a ship map depth, but seeing the seabed with cameras or submersibles is far slower and more selective — real progress has been made, yet the unseen remainder is still vast. A planet can be familiar on its surface and almost unknown just beneath it.

Aynı kart, başka bir dilde.

Okyanus tabanının çoğu hâlâ modern yüksek çözünürlüklü standartlarda haritalanmadı; ayrıntılı görsel keşif ise daha da azdır.

Sonar bir geminin derinliği haritalamasını sağlar; ama deniz tabanını kameralarla ya da denizaltılarla görmek çok daha yavaş ve seçicidir — büyük ilerleme sağlandı, yine de görülmemiş kısım hâlâ engin. Bir gezegen, yüzeyinde tanıdık, hemen altında ise neredeyse bilinmez olabilir.
