When a deep-sea rover moved across a quiet stretch of the South China Sea, its camera caught a pale cluster of rounded shapes resting on the seafloor at nearly 1,500 meters. The operators paused, thinking the objects were stones. But as the rover’s lights strengthened, the smooth glaze of porcelain appeared, arranged in what looked like organized layers rather than scattered debris.
The find emerged during a survey led by the National Cultural Heritage Administration, which has been documenting underwater cultural sites since last year. Crews on the vessel reviewed the initial footage and marked the area for a second dive. The depth alone made the discovery unusual. Very few known Ming Dynasty shipwrecks have been located in such deep water.
A new descent confirmed the objects’ identity. The porcelain showed clean surfaces and little visible damage, unusual for artifacts exposed to deep-sea pressure for centuries. Many pieces retained their form, allowing researchers to begin identifying them as products of well-known ceramic centers.
A Seafloor Covered in Preserved Porcelain
As the rover expanded its survey path, the scale of the site became clear. Later designated Shipwreck No. 1, the area held over 100,000 artifacts, primarily porcelain. According to the NCHA, many items remained neatly arranged, suggesting they had been transported as cargo rather than scattered by impact. The pieces included bowls, dishes, jars, and censers associated with mid-Ming export production.
Official data from the National Cultural Heritage Administration (NCHA) confirmed that researchers identified several artifacts originating from the Jingdezhen kilns, a major center of porcelain manufacturing. Decorative features and forms matched those documented in museum collections. The preservation of the pieces was attributed to low temperatures and limited disturbance on the seafloor.
A short distance from the porcelain field, sonar imagery revealed a second group of objects. These were longer, straighter, and uniform in shape, prompting investigators to widen the search zone. The organized placement suggested another cargo site rather than random seafloor debris.
A Second Wreck With a Different Cargo
The new area became known as Shipwreck No. 2. Instead of ceramics, the rover found large timber logs, stacked in rows. This arrangement, confirmed by multiple dives, aligned with descriptions of bulk wooden cargo carried during the early Ming period. The logs appeared well preserved, with surfaces intact despite long submersion.
An official statement from the NCHA noted that Shipwreck No. 1’s porcelain reflected export activity, while the timber found at Shipwreck No. 2 represented imported goods, indicating that the region supported both directions of maritime exchange. The contrast between the two sites allowed researchers to view the pair as complementary evidence of Ming-era trade.
Teams used the deep-sea submersible Fendouzhe for detailed recording. The vehicle documented the cargo positions without disturbing the arrangement, producing high-resolution imaging that will support long-term analysis.
How Researchers Analyzed the Two Sites
According to NCHA archaeologist Zhou Wei, stylistic details on the porcelain provided key dating evidence. Many items matched mid-Ming forms used in large-scale production. The intact nature of the ceramic stacks supported interpretations that the cargo had remained largely undisturbed since the ship sank.
Shipwreck No. 2 received similar scrutiny. The logs’ dimensions and ordering were consistent with historical accounts of timber imported from overseas regions during the early Ming period. These materials were often shipped in large quantities for construction and shipbuilding needs.
The combination of export ceramics at one site and imported timber at the other matched patterns described in historical documents. Livescience and official Chinese reports noted that the two wrecks together reflect active two-way maritime trade, a detail supported directly by the cargo contents.
A Clearer Picture of Ming Maritime Connections
The discoveries strengthened researchers’ understanding of deepwater routes used during the Ming Dynasty. Both wrecks sit along a corridor known for long-distance shipping, and their cargo types align with recorded economic practices of the time. The NCHA reported that the sites offer “important evidence” for studying maritime networks and cultural exchange.
Preservation conditions at 1,500 meters helped maintain the cargo in place. Low temperatures and weak currents reduced disturbance, allowing investigators to map the spatial layout precisely. Such intact arrangement is rarely documented in shallow-water wrecks.
Officials highlighted that the dual discovery provides a rare opportunity to compare two different forms of Ming-era trade within a single region, each represented by a deeply preserved cargo field.
Continued Survey and Protection Plans
The National Cultural Heritage Administration stated that further mapping will use 3D imaging, remotely operated vehicles, and sediment analysis. These tools allow researchers to document the wrecks without retrieving artifacts prematurely. Excavation will remain limited, with long-term preservation as the priority.
Teams from the Chinese Academy of Sciences will join the analysis, contributing marine science expertise to studies of seafloor conditions and long-term artifact stability. The NCHA confirmed that both shipwrecks will remain under monitored protection as research continues.
